I'm using the March 11th SVN snapshot and I noticed that while you can certainly rename groups, it doesn't work very well. If you open up the groups tab on the left, right click on a group (_not_ selecting it with a left click), and select Edit Name, you get two problems:

1. Any tabs with that group name retain the old group name, even if you click on them later.

2. The current tab gets changed to the group that you just renamed (with the new name) as if you'd selected it with a left click.

Interestingly enough, neither of these happens if you edit the name of the group but do not actually change the name. I assume that there's a check for whether the group name changed.

It's obviously not a huge bug, but it seems undesirable. Aside from the fact that having the current tab change on you being rather annoying, the part that worries me in particular is that the group name on pre-existing tabs of that group is not renamed. I'd hate to think that we somehow have created a new group or have a tab that is no longer technically connected to a group. I suspect that it's simply a renaming or refresh issue with the tab, but if not, there could be interesting and undesirable side effects.

Indeed, this is broken since the GUI changes.

EDIT: fixed
