Maybe quite a boring and convoluted idea, but I suggest a type of square that you cannot place mimics or decoys. How about: walls, doors, obstacles, force arrows, open yellow doors and trapdoors, you cry. Well, on numerous occasions I have become stuck since I couldn't use any of them (e.g. a snake in a loop that you don't want to be killed by a mimic, with a red door puzzle in a separate part of the room etc etc.)
Sounds convoluted, yes, but there are times that it would've been useful. (In my current hold in progress for example). Plus, open yellow doors just don't look nice, especially when not linked to an orb and therefore count as an error in the editor.
