There should be a way to change a media player's volume, without accessing it. I know this feature from the app indicator of the volume manager and it would be matching to have it on the media player control, too.
I was actually considering to add it, given we even have a (so far unused) OSD specifically for that.
Git commit bd5619e0155a4977bb891c1f01218847cab2ef1b by Radek Hušek. Committed on 03/04/2018 at 18:24. Pushed by husek into branch 'master'. [Media controller] Add simple volume control Summary: Add simple volume control to Media Controller applet. Volume can by changed by: - mouse wheel on applet icon (3 % step), and - new global shortcuts (5 % step, unbound by default). There is no mute support currently (mpris interface does not have a mute method so we would have to keep track of old volume). Test Plan: Tested in daily use with Cantata and SMPlayer. There is no UI change.
