Folks, if you don't know about it, check it out! KDE Connect is an application you can install on your phone (Android, iOS, and others) which allows you to pair your phone with your PC and do various things, like send SMS messages from your PC, use your phone to do remote input and media control, transfer files back and forth, etc. It's killer.
My wife was trying to watch some YouTube videos on the TV today and they were absolutely killing us with ads, so we plugged in the Fedora laptop (which has Firefox with uBlock Origin) and she was able to run it from the couch.
Funny thing is, we don't even use KDE. There is a Gnome Shell extension called GSConnect which is fully compatible with the mobile KDE Connect apps. The iOS app doesn't have as many features as the Android app, but remote mouse and keyboard input is there.
Along these lines, she asked if there was a way to make the mouse cursor larger, and I was like UHHHH (knowing from experience that the solution to this problem was going to be fucked up). So I did a web search and figured out there's a GSettings key you can tweak, SSHed into the laptop, but before I could run the command she said she figured it out. It's in the accessibility settings.
