More user-friendly map note editor

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. :stuck_out_tongue:
