As the OP I would also like to second kgudge's request for Contol/Shift ability, especially in the variables list. I accidentially had a db script create 1300+ variables the other day
and would have preferred to eliminate them without having to "exit without saving" variables. I've also noticed that if I delete an entire group of variables by its header(?) they don't go away unless I close MLS and go into the db and delete them there.
