Seems to be working - boots up to language selection (which I believe is a "normal" app), but won't let me choose any - mouse clicks register for language selection, but not for the "next" button, keyboard: nada :( Cursor only updates on LMB held down (with mouse integration and without). I think there's more work to come back to desktop-ish user expectations.
