[BUG] sometimes, red links (for pages that do not exist) aren't red (for example, links to discussion pages in the header)
[BUG] when a page has been changed multiple times consecutively, only one change is shown in the recent changes
[BUG] the recent changes RSS does not contain changes in namespaces other than the default one
[BUG] sometimes, recent changes randomly appear, disappear or appear out of order (still have to reproduce this)
[BUG] no links in headings (see above)
[FEATURE] size of diffs (chars added/removed) like mediawiki
[FEATURE] sort by upload date in
WYSIWYG editor media chooser
[FEATURE] links to media files
[FEATURE] the version history lacks a "compare to previous" function for single revisions (like mediawiki)
[FEATURE] when viewing a single diff, there are no next/previous change buttons (like mediawiki)
[FEATURE] there is no Special:Contributions that shows all changes done by a specific user
[FEATURE] show the author of a revision in RSS
[FEATURE] only ~50 recent changes are kept, that doesn't seem enough

[FEATURE] hide own changes from recent changes
[FEATURE] no usable mobile interface
