Hey, that looks good. Hmm... Did you know that you can change what it shows by doing middle-click in the icon? (In this case Firefox). It will cycle between visualizer, title and artist. I can't test right now but how does that behave with this change?

Yeah... I didn't know about the middle click feature, it is broken let me try to fix that. Also is there a wiki or something there is so many features I just discover lol.

There isn't but I'll write one soon lol

Seems that when I initialize the stack and make it the center_child (of mpris_small if I remember correctly), the overlay just can't be seen. I tried to change the center_child to overlay on the go. Middle click behavior works now but overlay is just a black screen, I don't know if there is a problem I cannot see because I'm not used to the GTK.

This looks ugly, it needs some extra care (e.g. radial gradient underneath the text fades from center to out).

Hmm.. The visualizer doesn't work on my system Any Idea what's the problem?
