So basically a DM draft/notes section, where you can save it privately for the DM and he can "publish" it to the campaign when he's ready?
Ah, now THAT really is cool. Basically, a cloud-based notes system that you can then publish piecemeal as the fog of war is revealed? That's like having an online adventure module that you can work on when you have time and then reveal as you go along. Very cool.
Re: battlemat
Minimum functions:
- upload background image for map (link to something online is also ok but upload would be really nice; maybe set them to expire in X time with a way to request extensions to help with storage space?)
- grid overlay on map (prefer auto-generated grid that has column and row labels - X, Y, Z vs. 1, 2, 3, etc.)
- be able to hide/reveal map as necessary
- upload images for tokens for PC/monsters and battle effects (zones, etc)
- DM only control but all players can see what is revealed (obvious but thought I'd add)
Would be nice:
- mouseover tokens shows status (HP, current effects, marks, rounds left until disappear, etc.)
- invisible DM area for cloud-based note taking (monster stats, etc.)
