I think a selection of several clips should not be the same as a 'group'. I 
would expect the same behavour as for example in a drawing program: 
- select several items in a volatile group, as it is usually done by holding 
the CTRL key. The selection is cleared as soon as something else is selected. 
- declare permanent groups, which have to be 'ungrouped' explicitly. As soon 
as a member of the group is (soft-!) selected, all members are (soft) 
selected, too.

Since it should be possible to apply all actions of a clip also to a group or 
selection of multiple clips, I would say this would be the way to do it.

Maybe a new "group" context menu showing "create group" (= make a permanent 
group of a selection of multiple clips) and "ungroup" will be necessary.

Not sure what you mean by splitting a group. But with the permanent groups it 
should of course be possible to select several groups, merge them into one 
permanent group, etc.

That's what I would expect.

I hope what I suggest is not overkill... ;-)
