I like most everything about this EXCEPT for the fact that the tabs reload whenever switching groups. That's very annoying. For example, if I download something in one tab, wait for it to complete, switch to a different tab group, and then switch back, the tab reloads and the file start to download again. That's just one example of the annoying behavior.

If it wasn't for that, I would be satisfied and would stop looking for a better tab manager. As it is, the search continues.

UPDATE: A later version of this fixed the tab reload issue, so now I'm much happier with it.
