Minigalaxy plans to do that (they are adding features like crazy, after SteamDeck launch.
While I like GameHub much more and it has much better UI(and controller support), it's being left behind Minigalaxy with so many missing features and bug(flatpak support is bug-ridden mess). It's worth to follow their 'Issues', because they are working hard to resolve all flatpak issues(BoilR is doing that too). I guess most of their problems(solved and unsolved) affects GameHub too.
