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.

Is there still an advantage to doing it this way after the desktop Big Picture update? Is it different than using the controller configuration menu on the host PC?

I don’t think they care about this feature. Presumably, they don’t see enough people using it to justify properly maintaining it, much less improving it.

As others have said, Moonlight + Sunshine works much better. Add Moonlight as a non-Steam game on your Deck and set it to launch Big Picture directly on your host. That’s my setup and it’s pretty seamless. Ever since the Big Picture update for the desktop client, I forget I’m even streaming sometimes because the interface is the same.
