While I was at it, I checked out a nightly branch build. The new find toolbar and livemarks are pretty slick. Some images of the features are here. All of this was originally prompted by my avoiding packing, and a comment on slashdot. I had no idea what livemarks were - and google wasn't much help. I eventually found those above mentioned screenshots, but then thought I'd check it out.
They're pretty slick - livemarks are a special type of bookmark, that points to an rss feed. In your bookmarks, they show up as a folder, but the neat part is that the bookmarks in that folder are updated to match the headlines in the rss feed.
The find toolbar is kind of slick too, manly because the highlight functionality. I'm not sure if I'd use it as I mainly use find as you type. Might be useful for big picture type stuff.
Anyway, I settled upon the official 0.9.2 release, as the nightly wasn't quite there (didn't like my extensions, nor my theme).
