It's just a convenience app, but it's a pretty nice one. When I moved my main PC from Windows to Linux, I was definitely sad to lose the ecosystem of nice launcher apps (GOG Galaxy but also others like Playnite, Launchbox, etc). The dream for me is to have all my games in one cohesive library, and that's what these sorts of apps offer. On Linux I use Lutris for this and it's fine enough, but I'll definitely be taking a look at Galaxy when it comes to Linux.
