I know this is a pretty nice request probably, but I thought I'd float it out there. I just randomly found Roll20 and the one thing it's missing for a campaign that I'd like to run is being able to make certain things visible to certain players. I'm actually looking to run a large strategy game with a world map where each player can only view their 'portion' of the world map. Meanwhile as the GM, I can make the required changes/etc.
This would also have use in a campaign if you have particular players moving separate from the group etc. Similarly if you were running a game like Werewolf where you had an Umbra and Physical World layer you could toggle which players could see which layer. (or Shadowrun decking etc)
If this is already available and I don't know how to do it pleaaaaaase someone let me know, otherwise this seems like a great feature for me personally but I'm not sure if it's too niche in general.
