I use this on Gnome for a long time now, and one (perhaps) unintended feature, is that if I'm watching a silly "reel" like video which does not have any controls other than play/pause, I can actually control it and change the position via the phone.

I believe GSConnect uses MPRIS for this type of video control, so with an extension like https://github.com/sakithb/media-controls you should also be able to control playback without having to grab your phone.
