Was surprised to see an AppImage and did some digging:

• Looks like there's a current movement to make native nixpkgs for things that were previously AppImages
• Here's a sample PR packaging an electron-builder app for Nix.

[toast003]

Not familiar with building npm/electron stuff from source and looking at the pr it seems kinda complicated, but I'll try and see if I can get it to work.

[toast003]

I can't get this to build from source

EDIT: Yeah, I give up.
Can we get this merged as-is?

[SuperSandro2000]

I've dropped the merge commit from the PR because that usually only causes trouble.

You probably also want options.services.handheld-daemon.ui.enable to default to options.services.handheld-daemon.enable in nixos/modules/services/hardware/handheld-daemon.nix, and pull this package in when true.

[toast003]

I wanted to add that on a different pr, since you need to add handheld-daemon-ui and lsof to handheld-daemon's service path for the steam/gamescope overlay to work, but I guess it does make sense to have that here

[SuperSandro2000]

Maybe this should be wrapped inside the UI?
