Make the lyrics and visualizer a toggle instead of hover action

[aelunic]

I've been looking in settings anc couldn't find an option for it, so I'm assuming there isn't. It would be nice if I could click the lyrics or visualizer button and have it stay on without having to hold my mouse in the area. I like doing something on monitor 1 while having this on monitor 2, and will sometimes want to look over when I forget the lyrics I'm trying to sing.
