Tab closing - standard behavior

Not really a bug but not a new feature either, just a modification/optimization.

Current behavior:
When adding a tab to a group, it's placed to the right of all the other tabs.
When closing a tab in a group, the leftmost tab in the group is focused.

Expected behavior:
If you're adding tabs on the right, I think it's more intuitive to focus the 
next tab to the right of a closed tab (or the rightmost tab, if you closed the 
current rightmost tab).

That way, tabs can easily be closed in the reverse order in which they were 
opened, which seems logical. Compare with standard tabbed web browsers.

Tabs A B C D
Close D, focus C
Close B, focus C
