+Plotters
+--------
+
+-   <s>Speed up plotting on 16-bit screenmodes</s>
+    -   Think this is now largely irrelevant as font\_antialiasing:0
+        makes a huge difference. However, would like to add
+        hardware-accelerated anti-aliased text rendering
+        (CompositeTags() does not support ALPHATEMPLATE so this is not
+        possible at present - see also the chris/composite-text branch)
+
+-   Direct rendering - problems
+    -   inline image placement
+    -   grey background for all text
+    -   won't work with Cairo renderer
+    -   may crash with certain gfx lib operations (AreaFill - need to
+        alloc AreaInfo/TmpRas, check if this is ok to do on window
+        rastports or if one or the other is allocated already)
+    -   completely broken with tiled renderer
+    -   Will probably only leave this in for debugging purposes, has no
+        real use now.
+
+-   Text
+    -   Replace ligatures?
+    -   Use splay trees for font cache
+
+-   Simple Refresh
+    -   Dragging blocking windows (eg. About) over the top of a render
+        area does not redraw <i>at all</i>
+    -   Favicon and throbbers do not redraw when damaged (the redraw
+        functions just crash when they are initiated from the
+        hook/ami\_handle\_msg)
+    -   Change to \*queue\* redraws same as corewindows
+
+-   bitmap scaling
+    -   not always accurate
+    -   switching to triangle mode is more accurate, but causing
+        freezing at least on SAM440 with built-in gfx
+
+User Interface
+--------------
+
+-   Shiny new treeview toolbar
+-   treeview window redraw needs optimising
+-   Drag-related
+    -   Support the drag'n'drop of icons from/to OpenAmiga Filer project
+    -   Drag to hotlist from WB?
+    -   Drag selections within text input fields should do a move rather
+        than a copy (might be core bug?)
+    -   Clicks to become drags only after 5px or so movement (done for
+        treeviews)
+    -   Text selection should have auto-scroll ability at window's edge
+    -   Dragging text to the URL or search bar should immediately enact
+        that option
+-   Iconify gadget - for non-WB screens. Add extra AppIcons functions,
+    eg Info, Delete. Dynamic updates?
+-   Allow multiple homepages - see
+    <http://bugs.netsurf-browser.org/mantis/view.php?id=2270>
+-   Add play/stop buttons in sound DT handler
+-   Experiment with label.image in clicktabs (favicon; text in more
+    appropriate charset)
+    -   More appropriate charset also useful for hotlist menu, toolbar
+        and history context menu
+-   Use menuclass for pull-down menu
+-   Fix passing of commandline options to the core (NSOPTS/M)
+-   Use new Ringhio progress notifications for downloads (if we can
+    upload the header)
+
+Core windows
+------------
+
+-   Share off-screen bitmaps (with browser etc)
+-   Allow simple refresh windows
+-   Optimise redraw (on scroll)
+-   Drag select redraw not working correctly
+-   Regression: dragging from global history no longer working
+
+popupmenu deadlock blockers
+---------------------------
+
+These need doing now a bug in popupmenu.library has been fixed.
+
+-   Context sensitive help
+    -   Add Help key processing in gui\_options.c and anywhere else
+        needed (local history, treeviews, etc)
+    -   <s>Fix asynchronous close signal thing now but is fixed in
+        lib</s> - doesn't appear to need any changes, AFAICT I didn't
+        bother working around this bug
+
+Misc
+----
+
+-   <s>Switch to malloc/free so OS3 gets full benefit of clib2's slab
+    allocator</s>
+    -   <s>should have no impact on OS4 perf, but may be worth
+        abstracting this so we can switch and change easier in future
+        (unless it makes the debug info from clib2 useless... hmm...
+        maybe use \#defines)</s>
+    -   when done, enable clib2's debug mem handler: "The settings for
+        the memory debugging layer can be found in the
+        "stdlib\_memory.h" header file, right in the first few lines.
+        Just uncomment the lines for "\_\_MEM\_DEBUG",
+        "\_\_MEM\_DEBUG\_LOG" and "\_\_USE\_MEM\_TREES" as needed."
+    -   Enable stats collection so we can tune the slab size - see
+        <https://github.com/adtools/clib2/blob/master/library/include/stdlib.h#L190>
+-   <s>Reduce signals usage (if possible)</s> - believe this is no
+    longer an issue
+-   Replace ExAll() usage in menu.c with whatever the new OS4 equivalent
+    is
+-   Font styles in clipboard (might need new chunk defined)
+-   Revamp About requester
+-   Add a low memory handler which calls llcache\_clean(true). Need to
+    somehow guard this as it isn't thread-safe (set a "ok to clean",
+    "clean in progress" flag which is set/cleared/blocks the GUI?)
+    -   MEM\_TRY\_AGAIN might help, return this until safe to purge, or
+        until purge can happen in main loop
+    -   <s>Safe to do this to call \_\_free\_unused\_slabs() on OS3</s>
+-   <s>Ditch libauto</s>
+    -   Hopefully this fixes starting NetSurf on OS4.0 - program is
+        apparently terminating before it starts running any code. Unable
+        to test, awaiting feedback from the person who reported
+        problems.
+    -   See also
+        <http://www.amiga.org/forums/showpost.php?p=773311&postcount=9>
+    -   Probably doesn't work on OS4.0, as I saw a note that random()
+        needed a v53 newlib.library when rebuilding the toolchain
+
+OS3 Support
+-----------
+
+Please see <http://www.amiga.org/forums/showthread.php?t=56813> and
+<http://amigaworld.net/modules/newbb/viewtopic.php?topic_id=34237&forum=27>
+for various discussion around this topic, as well as
+<http://www.amiga.org/forums/showthread.php?t=63990> for more recent
+updates.
+
+NetSurf will now build for OS3. For a quick start on building NetSurf
+see [[OS3 build notes|documentation/buildingforamigaos]].
+
+There are some outstanding known issues:
+
+-   Fonts
+    -   There seems to be a (lack of) spacing problem with some fonts.
+        May need to manually add OT\_SpaceWidth?
+    -   Bitmap fonts (with limitations, ie. no UTF-8) support partially
+        working - line break detection is broken and sometimes causes an
+        infinite loop. (is this still the case?)
+    -   The font scanner might be broken.
+
+-   Plotters/Bitmaps
+    -   We are currently ignoring the p96 stuff and treating all screens
+        as palette-mapped. This works but means the faster direct 32-bit
+        bitmap code is not being used when P96 is available. If we take
+        the P96 path, bitmaps work but everything else is rendered
+        unreadable.
+    -   PDTM\_SCALE (used when getting palette mapped bitmaps) only
+        works on v45, need to use BitMapScale for OS3.5 compatibility.
+        (this might be fixed since guigfx change?)
+
+-   GUI
+    -   Tabs working but closing them causes NetSurf to crash.
+    -   The status bar is not in the window border (frbuttonclass is
+        irredeemably broken in OS3)
+    -   A lot of the GUI hasn't tmk been tested.
+    -   The treeview windows eat memory for breakfast (might be better
+        now using corewindows with tiles and simplerefresh option)
+
+-   Memory freed twice (recoverable alert 010000009) on exit
+

+
+Bugs
+----
+
+General
+-------
+
+-   Use pointer hot spot data.
+-   Can't press and hold a key to get auto-repeat. e.g. for delete.
+-   local history scrolling does not work
+-   url text input widget is not great
+-   crash with x frontend with some wm
+-   animated gif/internal font render funny
+-   obscured widget ordering issue
+-   Need a text cursor.
+-   Use path plotter and LibSVGTiny.
+-   Support page scaling.
+
+nsfb wrinkles from RJEK
+
+-   URL bar text size seems... overbearing.
+-   Home toolbar button?
+-   Local history thumbnails are all black
+-   On-screen keyboard gets overwritten by content.
(It might be worth
+    rethinking how this works. How about the keyboard taking up the
+    whole screen with its own entry box, and then inserting that text
+    when the user is finished? Android does it this way when screen
+    space is tight, and it would eliminate the problem of having to
+    scroll the content so the text area is visible with the keyboard
+    open.)
+-   You can't grab the scroll handle when it's really small (try HTML5.)
+-   No dragging support means it isn't as nice to use as it could be on
+    touch screens.
+-   Form buttons don't work on the Joggler; strangeness on how the touch
+    screen delivers the events?
+-   When configuring the scroll bar size, the arrows become distorted.
+    Perhaps draw them using the drawing commands, rather than using
+    images?
+-   At high-resolutions, the OSK's key bevels are so small in comparison
+    to the keys they're essentially invisible.
+-   Pressing the arrow keys on the OSK to scroll causes the
+    newly-redrawn document to obliterate the keyboard.
+-   When loading a page, the arrow adds an hourglass. If you do not move
+    the mouse after this, the hourglass remains until you do. (Repaint
+    the pointer when the throbber stops?)
+-   The stop/refresh buttons don't grey out when unneeded. (ie, the stop
+    button isn't needed when the throbber isn't going, and the refresh
+    button isn't needed when it is. Some browsers combine them to save
+    space, ie the button is a stop button when loading, and a refresh
+    button when not.)
+-   No caret drawing.
+-   Lots of libnsfb/fbtk debug output; have this runtime selectable?
+-   Can FreeType be auto-detected and used if available at build time?
+    Our Makefile.config stuff would still allow this to be turned off
+    should the user want it.
+-   Mouse input becomes laggy/follows movement some time after the real
+    movement, when loading occurs. Is there any way to prioritise mouse
+    inputs, or drop pending movement when a new movement event comes in?
+-   Aesthetic only: Can we get anti-aliased line drawing on the local
+    history window? :)
+-   Go to Wikipedia. Scroll down using the wheel so the logo and
+    logotext in the top left corner is no longer visible. Slowly scroll
+    up only enough to get to the top of the document again. Scroll up
+    once more, and note the logotext change position. (It moves up a
+    couple of pixels.)

+Code quality/Organisation
+-------------------------

+-   We should probably test with -DG\_DISABLE\_SINGLE\_INCLUDES
+    -DGTK\_DISABLE\_SINGLE\_INCLUDES to check for GTK 3.0 compatibility
+-   Also worth checking with -DPANGO\_DISABLE\_DEPRECATED
+    -DG\_DISABLE\_DEPRECATED -DGDK\_PIXBUF\_DISABLE\_DEPRECATED

+
+Core Treeview
+-------------
+
+Updating the front-end to work with the Core Treeview changes. Largely
+complete, the following items are either low priority (?) or waiting for
+other changes such as the toolbar widget re-implementation.
+
+This work is (at present) in the trunk.
+
+### Outstanding work
+
+-   Should the font used in treeviews be configurable?
+
+-   Textarea code should call the front end to render the caret. (Like
+    the form code.)
+
+-   Hotlist editing dialogues need to be reinstated, or all associated
+    templates and code need to be removed.
+
+-   URL Suggest Menu module may require re-implementation as a
+    stand-alone entity which collects URLs entered directly into the
+    address bar and Open URL dialogue, instead of relying on URLdb. Low
+    priority?
+
+Toolbar Update
+--------------
+
+Updating the toolbar implementation to break the component parts into
+stand-alone widgets. This will serve two main purposes: allowing some
+outstanding Core Treeview issues to be closed off cleanly, and allowing
+additional features to be added to the GUI without the risk of breaking
+the existing components.
+
+This work is underway in /branches/stevef/toolbars.
+
+### Niggles
+
+-   Toolbar menus shade unsupported widgets, instead of hiding them.
+
+-   Check and confirm the correct content types for
+    ro\_gui\_url\_bar\_set\_site\_favicon() to accept from the core.
+
+-   URL Completion needs to be migrated from the Window module towards
+    the Toolbar / URL Bar modules.
+
+### Further improvements
+
+-   "Unlimited" length URL field in URL Bar Widget.
+
+-   Tab Bar Widget.
+
+-   URL Suggest module could identify menu availability more
+    efficiently.
+
