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.)

What do you use to send YouTube links to FreeTube? Personally I’m using LibRedirect https://libredirect.github.io/
A few years ago, the UK Justice Minister called for a ban on the sale of tiny, lipstick-sized mobile phones that came with a voice-changing function built in. (Article) They were being smuggled into prisons and the convicts were using them to commit crimes from the inside, including making intimidating phone calls to witnesses etc.
What a sad day that would be for legitimate rectally-insertable, voice-changing cellphone enthusiasts!
