Change button colour when switched

Hello everybody!

First, thank you to the developpers for this fantastic live extension.

Then, is it possible to make the colour change in a button made in editor when the associated function is activated, like for a mute?
On my windows 10 tablet, each time i tryed to undo, the app freeze and i have to restart it, is it still a beta function or I’ve forgotten something?

Thank you to help me.

Hi again. Well It’s okay for the freeze, I just have to wait a while…
