I was loving this, until I lost all groups when coming back to work today, all was fine Friday... I'll try redoing them, and after looking in options I saw there are backup/restore options, I hope it works, else I'll have to fine something else.
Edit: finally I saw there are automatic backups and was able to restore last one, give 4 stars, not 5 that would have been if I did not lost all groups in the first time.
Edit again: I should have looked better, yes all my groups have been restored, counters of tabs seems good, but there are missing tabs, when I change group it just jumps to a tab keeping others (from other groups) open, and do other weird stuff... And now its even worse that before I restored... Too sad...
