Okay, this is pretty much complete for the features I wanted, there's no checking or editing of friends or friends groups yet (wait for v1.1.0). But it's been bug-tested and looks very cool.
YaxJournal is the 6th. most popular client for LiveJournal now, so if possible could it gain a link from the LiveJournal download page? If there's anything that you guys require me to do before that can be done, I'm sure I can oblige, e-mail me.
