Changing list order of groups

Is there no way to rearrange the order of contact groups rather then having them alphabetically? In Pidgin, groups can simply be dragged up and down which makes sense.

I would settle for being able to rename existing groups if they have to be alphabetical, but I can't find a way to do that either. Right-clicking on a group name only produces the option "Remove" but not "Rename". I considered creating new groups that started with numbers ("01", "02", etc.) to get my groups in the order I want and then moving all my contacts into those but that take more time then this should require.
