Area Effect (AOE) Markers

If a player has cast wall of fire, it would be wonderful if there was a tool (similar to the current measurement tool) to set and leave a visual area of effect. Currently for any concentration type spells or natural effects (i.e. a spreading fire), I've resorted to using innocuous props as a guide for the marker.

The current measurement tool, namely the spherical tool, seems to function exactly as I'd like the requested tool to. Notable differences are that you cannot change anything on the board or move the tokens while the current measurement tool is active - this makes interacting with any measured effects very tedious and abstract.

The mechanics are already in the program to see this function- well... functional. It's down to the actual application of the existing mechanics for use as visual indicators of AOEs.

If not a standalone tool, simply allowing use of the measurement tool while also moving tokens and doing turns would solve a good deal of this problem. Additionally, allowing multiple measurements to be on the table while still being able to play would be perfect and make unneccessary a seperate tool.

Thank you for reading!
