That sounds good to me.  It also fits well with common UIs in other 
editing programs (office automation, image editing, etc.)  I don't want 
to lose the new design Mark used, though--the one that makes it 
impossible to create an invalid cut list through the UI by adding 
discontinuities with redundant start/end marks.  With this approach, 
what the user sees is what the user gets, and we never write invalid 
cuts to the database (nor silently modify the cut list the user saw 
before writing it to the database).

Thanks,
Mike
