the controls for the group disappear from Navigator
Ideally Navigator panel will update to show the group and controls in the group, as does the IDE.
This may be tricky. FWIW Mark Waddingham an a separate thread on the list explained
"Indeed, 'start editing group Foo' causes the engine to remove all cards
and objects from a stack and store them somewhere self, create a new
card and add the controls that were in the group as the new card's
objects. Which is obviously a great deal more work than just moving a
control somewhere else in the internal lists."
