Lights and gm painel

Hi, I just discovered the program and I already think it's amazing, your work is very good! The only thing I would like is a feature to turn off all the lights and change their color, or if possible, turn off all the lights in a specific room, like a GM panel, that would allow you to turn off these lights, perhaps from the top of the map, as well as change colors, move NPCs, etc. It would be very useful.
