I dunno about other people but I play docked a lot, and typing with a controller is near unbearable sometimes. I specifically had this thought because I was playing webfishing from my couch and thought it would be nice if I could pull out my phone and open the steam app, or maybe they could make some kind of steam deck companion app for this and other features maybe, to quickly type a message or just make typing easier. I dunno if this would be difficult to implement or even possible but I think it would be neat.
I haven’t tried it, but I’m pretty sure I remember seeing a decky loader plugin for it!
Yes, it works in gamemode. You might want to also get the Decky loader plugin that lets you control KDE Connect is enabled from gamemode though
It didn’t work for me last time I tried, but yeah, it could have been fixed by now. It’s definitely the right direction to try, it’s the perfect solution for OP.
