Version: (using KDE Devel) Installed from: Compiled sources When JuK is minimized to the systray, it is very convenient to use the global hotkeys to change the volume without having to open JuK back up (as volume can vary greatly from song to song while on random play). I think it would be very handy to have some kind of visual indicator that pops up when you change the volume though (but only when you are changing the volume while JuK is minimized).
This is now present in KDE Plasma 5.24, so I'm marking this bug resolved.
