The map note system is not the easiest IMO. Could be user-friendlier, such as:
Red M Minefield
Blue I Ice lab
Brown C Car that’s still being a POS
M Minefield (default yellow, M, reads “Minefield”)
Minefield (default yellow, default N, reads “Minefield”)
Doable? I mean, we COULD come up with something even MORE obfuscating.
