I've finished the version 4 of my livejournal-post widget.
It features:
- md5 password sending to livejournal
- itunes music detection (artist/album/song)
- mood setting
- login/password storing
- friends only/private/public options
- community posting
- last post view
- livejournal flat protocol
- utf-8 posting support
I think that I've fixed all the bugs and implemented most of the features I've been asked about.
