Option to hide ruler measurements as DM

What Feature would you like to see included within TaleSpire?
It would be great to add toggle to make measuring hidden as a DM

What situations would this Feature be useful?
This would mostly be handy for combat when creatures are invisible. I recently ran combat where a creature was invisible and I needed to see how far it could move or cast spells without the players knowing it’s location.
