Player Movement Approval: I would like an option so that players who are allowed to control their characters can submit to the DM a movement choice and the path/final position is shown in highlight until the DM approves it.
Lockout/Authorize: I would greatly like the ability to lockout all drawing/map modifications players can currently make. If they want to mark something, there could be a dialog box showing the player is asking permission to mark up the map. The same for the cards or adding any new tokens to the map.
Movement Pathing & History: It would be nice if you could select a trace path option and show movement as non-linear...so going 15' east then 10' north. In addition, some kind of marker showing where the token started would be helpful...maybe until a 'confirm move' dialog box is checked?
