This literally took 15 minutes, but it solves something that has bothered me (a little bit) for a long time.
Sometimes I want to quickly switch where my audio goes to. From headphones to speaker, or to bluetooth, and so on.
Well, just trigger this and choose: Rofi Sound Picker
Requires a number of things (see the README) and it may make sense bound to a hotkey if you are using a window manager. If you are using a desktop like Plasma, the mixer icon already does it.
It should "just do the right thing", do nothing if you cancel, show the correct item selected on start, and so on.
