I just downloaded 0.8.0 from 0.7.2. I use a wired Xbox One controller.
In 0.7.2 (and earlier) versions, I mapped Mute to left bumper and Fast Forward to right bumper. I could toggle them by hitting the relevant bumper.
I attempted to set up 0.8.0 identically, but it doesn't work. Both only activate while the bumper is being held down.
I do not have a shortcut set for Fast Forward (Held).
