Let admin predefine buddy groups

I've got a well working local solution to solution to show some buddygroups even if the user hasn't defined one yet. And I would like to share it. Currently, there is no user interface for that, just the feature. But I could work on that. My solution is the following:

In the database buddylist_groups table I set some groups and set uid to 0. Some Database queries are adjusted so that groups having uid=$user->uid and uid=0 can be selected. Deleting of buddygroups is restricted to those of own uid of course.

If new users find predefined groups, they know better how this works. Defining own groups could be made a premium feature that you could restrict on members of a certain role, so I would define this role too. Also there is no need to put the "add buddygroup" and the "delete buddygroup" sections on top of the buddy-buggygroups-list on the "Edit groups" tab. Having alway the most important information on top, they should be moved below the list.

If you like this feature, I would port it to the current dev version.
