* Use Javascript to improve the downloads page, by only showing the most important ports/downloads by default, and then uncovering the rest upon a click by the user (with gracious fallback if Javascript is disabled). A first draft of something like this can be seen on http://fredrik_w.users.sourceforge.net/downloads/
* Change all screenshot filenames to match our rules as described [[Screenshots|here]]. E.g. rename <code>data/screenshots/agos/simon/scummvm_2_4_0.jpg</code> to <code>data/screenshots/agos/simon/simon-0.jpg</code> etc.; also some stuff should maybe be moved to other directories.

==== Iterator handling ====
* Implement proper reverse_iterators for Common::List. Our current implementation is the same as forward iterators, just that rbegin will return the last element instead of the first and there is no rend. Check [http://www.sgi.com/tech/stl/ReverseIterator.html SGI Documentation] for proper description of revese_iterator in the STL.

==== Event recorder ====
Currently there is an implementation based on {{PatchTrack|num=1214168}} but it needs more work
* Try to avoid warpMouse() calls at playback, so the system will be useable
* Perhaps we need to indicate recording mode. May be draw triangle/circle in some corner. Use OSD overlay for that
* Still it is possible that time will drift away even with current implementation. Do something about it, at least try to detect
* Remove temporary file
* Perhaps autogenerate record file name based on target name
* Perhaps combine 2 files which get created currently into one
* We should store unique game ID in the record files. I.e. ideally it should be engine name and some game MD5 or anything else which could be re-generated on game start. Then when this method is called in playback mode, recorder matches this against values stored in the record and refuses to play if they do not match.
  registerGame("scumm", "60ba818dc3bede86d40357e3913f8505");
* Perhaps add special flag when game started from a save, i.e. not from the very beginning but with -x command line switch
** Perhaps embed the save into the recording then
* getMillis() currently is hacked into SDL. It has to be moved one level up
* delayMillis() perhaps has to be wrapped too, so time drift could be avoided

=== Error handling ===
Sometimes, bugs are reported that are not easily reproducible, e.g. [https://sourceforge.net/p/scummvm/bugs/6751/ Bug #6751]. In such cases, it would be useful to have the error handler in ScummVM generate (and, optionally, automatically send) minidumps that can be used by us to successfully examine crashed ScummVM processes. Integration of something like [https://chromium.googlesource.com/breakpad/breakpad/ Google Breakpad] is one reasonable option. While it is not likely to be able to get such crash handling into all ports, just supporting the most popular platforms would be enough to make this feature very useful.

=== SDL backend ===
=== SDL backend ===
* Right now, the WinCE and the Symbian backend subclasses the regular SDL backend. They both overload a lot of methods (mostly the graphics stuff). Since graphics.cpp uses the scalers (e.g. hq3x), these derived backends carry that baggage around, too, even though they don't need that code. Idea: split the SDL backend into two classes, one base class which only has the code which is used by all subclasses; and a "desktop" subclass, which implements the rest. Then WinCE/Symbian would only subclass the "base" SDL class.
