Thought about this as I was going through old snapshots in a foggy game to determine where players were. It would be neat if there was a tool to somehow assign a color to foggy regions on the map, to mark where you think/know players are. Maybe a colored box could display around the question mark. It would be more efficient than scanning through tons of snapshots & chat notes, and make things much easier on "visual" people.
Yes I would love this, very hard to keep track of some games, especially if you have a series of the same map, its hard to distinguish them apart sometimes and remember without goign through each snapshot
