There is a more recent version of juhu, please download that one - 0.6.5
this one took a little bit longer to come around, because on the one hand my spare time was occupied otherwise and on the other hand cocoa split views didn't want to make friends with me out of the box... nevertheless here it is!
the main work went into something pretty unspectacular - juhu scales now. you can resize the window and make the boxes bigger or smaller. nice, but there is more - sometimes I posted comments as normal posts, or simply mistyped something - going to the jaiku pages only to delete a post... mh, not the best solution, right? so I added a delete feature for posts and comments (trash icon beneath a post), I use quite a lot. besides the always todo bugfixing and some smaller changes within the interface (re-organised icons, etc.), I also added update notifaction - so if there is a newer version, juhu will tell you from now on (to disable that, just go to the preferences and uncheck the box)
enough said, now it's your turn. try it and tell me what you think, what you like, what you don't like or what problems you have using juhu. I'll try to help where I can.
juhu 0.6.3 can be downloaded here (via google 421kb). the complete source code is available at the google code page.
