Ziegmaster, if someone can help implement a hotkey, a tooltip should also be added, similar to the one on the main button. Something like this, but with a font, color, and wording of your choice.

Regarding the button itself, the transition from passive to active occurs not only with a color change but also by pressing it down and then returning it to its original position. However, when transitioning from active to passive, only the color changes. It might be intentional, but on the main button, for example, "Another World" (Dungeon), it always presses down and returns to its original position with each click.
