Rated 1 out of 5 stars
very good idea, nice visualization - would be a great feature if it would actually work.
doesn't update properly, if you move messages from inbox somwhere else, or send drafts. Sent messages won't gent indexed at all. So in my setup, the index times out every day for the most recent messages, which is basically useless. Alternatively you have to rebuild the whole database every time you want to use threadvis.
Conclusion: not usable for me.
Maybe I missed something? For me it's hard to explain why there's so many ***** ratings...
