I've seen Gear Lever mentioned, but I can't get past the fact that description says Gear Lever targets Flatpak usage. I'm also finding that all the various desktop integration and automatic (decentralized) appimage updating solutions sort of runs counter-intuitive to the whole "one file to rule them all" nature of AppImages in general. My only real interest in AppImageLauncher was to see how Sigil behaved with it. But to each their own!
