I wish you implement "select last active tab after closing current tab" feature.

I have tried 2 other addons that bring this functionality, but they both conflict with your addon:

When I switch from group A to group B and then close active tab in this B group - I am switched back to A group. That works like it should be: last active tab was that one in A group.

But if I switch back to group B again - then any active tab from A "moves" to group B.

:(
