There is a more recent version of juhu, please download that one - 0.5.8
time for another release. like always I fixed some minor bugs and issues. and there is a new featureon the interface side of things: hotkey support! right now you can only use the default key combination ⌥⌘J to activate/deactive juhu - but hey, it is a hotkey, right? however, I plan to make this costumizable with upcoming releases. and last but not least: I readded the lost two icons - the bike and the toaster. so just download and have with juhu and jaiku on your os x desktop.
juhu 0.5.2 can be downloaded here (via google 369kb).
you can get the complete source code from the google code project page.
