1) One of the things that I would find very useful, would be a text box, for flavor text, to go with each map. I know I can post directly from FM8 to SM, to show maps, but there is not a way, that I can find, to do the same thing for text items from The Keep.
2) Text input for map annotations. I would like to be able to have standard text characters (letters and numbers) available for myself and my players to annotate the map. This way, I could number treasure chests or whatnot (making it easier to determine what is where) and so my players can mark their targets (each character using a different letter).
3) I do not know if this already exists, but if not, I'd like it to. The ability to save revealed portions of a masked map. This would help immensely.
