Okay, first of all, a few people have downloaded the kde client ... it's intended as a "proof of concept", it's not as lightweight as I'd like.
Also, 0.01alpha is marked as "not for public consumption", and you've all no doubt found out why. 0.02alpha, due out later on today or tomorrow, *will* be usable. I'm using it now.
Please file bug reports in the tracker. If you think there is a new innovative feature you want, feel free to submit a feature request, but of course I'm still adding many obvious features.
