Yup, my only complaint is that Steam Deck controller doesn't seem to work automatically with Heroic games launched through desktop mode, and most guides I see recommend running games through Steam.
If Heroic had smooth integration with the Steam Deck, I'd use it a lot more.

If you hold start for 1 second in desktop mode you can switch between Desktop and Gamepad profile (which should just emulate a regular gamepad), assuming you don't mean that.
Looks like TL;DW - rewrite Heroic in Rust, and rearchitect it a bit to more easily support other stores than GOG and EGS. There's also an intro to other options.
Eh, I think something like Electron makes a lot of sense, but maybe they'll go with tauri instead if it's going to be written in Rust. The app itself isn't really performance sensitive since it basically just launches games in another process, so using a web view isn't really an issue, and could even be helpful in order to handle 2FA and whatnot.
So I wouldn't expect them to rewrite with GTK+ or Qt or something, but who knows!
