What sucks - Hatta Wiki

What sucks?

The markup is not exactly Wiki Creole.
If you use weird characters in page titles, they get %-encoded in the filenames.
No extensions or plugin system.
If you run it on your server and push from local copy, you need a mercurial hook for updating the server copy (or run hg update manually on the server) – this is fixed in 1.6.0. Also the "History" page will not be updated until the first search or edit has been done.
Types of pages are recognized by the file name (extension, to be precise). If you upload an image in a file without extension, Hatta will try to display it as a wiki page…
Diff for binaries is pretty useless.
No gallery, forum, bug tracker, message board, blog, news gate, e-mail client or movie player. Only wiki.
No InterWiki or LocalNames yet.
No cool macros for things like including pages, including feeds, displaying statistics, searching the wiki and such. All pages are dully static unless edited.
No WYSIWYG editor.
No AJAX, collaborative editing, on-the-fly updating of recent changes and page history, not even cool animations.
Default style is a little uglier than this one.
No library of ready to use styles yet.
Page history is not displayed as DAG like in HgWeb.
All the Issues.

By the way, feel free to add to this list. Except for bugs, which should go to Issues.
