Oh cool, I didn’t realize that was possible. That would be a great reason to use the plugin. I never really play non controller supported games with the Deck, so I just have the track pads set to mouse and scroll for the occasional desktop task on the host and the paddles set to Moonlight shortcuts.
I’m the same: I used it a ton when I first got it and now it’s collecting dust. Here are my personal issues with it:
I guess I essentially just wanted a Switch that could use my Steam library for 2D indies and older games.
Aside from that, I think I also kinda bought it to rejuvenate my interest in gaming, but it only did that for a few months. That has nothing to do with the Deck though.
