The current provided desktop mode is rudimentary, and mostly working. But it has so much potential. We could have all in one device with us, and just plug that into an usb-c dock. Or watch things on big screens in hotels if a mouse emulation on touchscreen like samsung would be supported.
Or, as Samsung already has created this, maybe that could be somehow ported to GrapheneOS via some 3rd party patcher? I'd really like to use samsung clock and gallery, as well, as those are quite a lot better than AOSP ones.
I like GrapheneOS, and the promise of it. Just a few minor things and it would be awesome instead of really good.
