Basically, what I'd like is an additional GM layer. The GM layer is fantastic for putting an overlay over the map (for example, trap locations, room numbering, room names, etc). It is also fantastic as a place to store monster tokens until I drop them onto the map. Unfortunately, it is bad at doing both of these things at once. If I store my overlay on the same layer as my tokens, it is almost inevitable that I accidentally drop the info overlay onto the objects/tokens map when trying to move an orc into active use. Anyway, a second GM layer seems like a fairly easy thing to implement, and it would make my life way easier.
