...Working with points, I think that something like "Select Conected" function but for the groups it'd be more quick and effective in time than go to the group list, find it (between that chaotic 
Moho listing way) and select it... With "Select Group/Grouped" you only should select a point or points that you know belongs (a very intuitive thing) to the desired group that you want select and press the shortcut, that would be all!
