KDE Connect
I've used it a lot just to control audio or video playing on my computer from my phone. (Sometimes when I'm sat at my computer with multiple windows and workspaces open, I even find it easier just to hit my phone's lockscreen to pause the music.)
I'm starting to use some of its other features, too. E.g. copying & pasting and sharing files between phone and computer.
There's more too I need to explore.
(Unfortunately, sometimes I get a 'device unreachable' error when both devices clearly have a working connection to the same router.)
