I've been testing more and more features of kde4 lately, and have noticed some things I'd like to fix if I had the time... I'm betting others have some of these also. I'd really like to fix up kttsd and get it working well again, as that is one of the things I miss from kde3 (listening to irc, etc.) It is somewhat working now, but could definitely use some love. Seems the maintainer ported it while kdelibs was in fluctuation, but there are still some things that look like they were written with Qt 3. Other kdeaccessibility apps could use some ui love also, simple things like finding out why &Language: can't be a buddy of a KLanguageButton in the kmouth setup window, etc.
I almost wonder if other devs have these side projects in their mind they'd like to work on also, if we should start pointing people to a page with junior jobs, or side projects we could help a newcomer figure out and maintain. There's a mentoring site here: http://www.kde.org/getinvolved/development/ that we could use, or something on techbase could be made possibly.
Anyway, I think we are doing great work, but we could use a few clones ;-)
