hide aoe markers

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.
the ability to hide and attach persistent aoe markers to creatures (Edited by dev, see comment)

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

the ability to hide AOE markers would be wonderful for marking areas for traps to be triggered. and attaching them to a mini/creature could help with many things like auras and other spell effects. say keeping track of who is in the range of your detect good and evil/thoughts without cluttering everyone else’s screen or without showing your players. (also you dont have to keep moving it when your character moves)

Additional Thoughts/Details

another cool idea could be for stealth indicating line of sight for guards etc.
