Correct.  They are already mode specific.  Still I might need to change
others and would have a good system.  It would also help others making
modifications without having to figure out what to do.

Still, as you suggest I can code tho part for mode specific faces differently.
Then others can find a number of different constructs to learn from, rather than
just one way that simply solve mp problems.
