Hide boards from players

What Feature would you like to see included within TaleSpire?
What does it look like, how does it work, how is it used. Paint us a figurative picture.

 I don’t want the plays to see some of the maps I am making. Yes i could change the map name and use the hide land feature but that is not a long tern solution. Eventually I hope there will be a way to organize maps so for long campaigns(so folders and if that is not already requested ill add it). In my TOA campaign I had 60-100 maps and that would be way too much for Talespire Rn.

What situations would this Feature be useful?
Descriptions, examples, interactions with existing features - whatever you can think of to get your idea across!

 Map origination and control for the DM
