...but 3.0b is working fine for me. I've seen a few small bugs, but no show-stoppers. Yeah, it would have been nice for 2.x to persist alongside 3.0 (or to be able to dynamically switch between the two), but whatever. Rearranging tabs and expandable text boxes are nice features. The page loading also seems snappier for me. Good stuff. It breaks Pithhelmet again (and crashes if you hack the Pithhelmet info.plist file to get it to load even though it wasn't tested with 3.0), but I'm sure that'll get fixed eventually.
