I find Appimage to be better alternative to Flatpak: no install, persistent through linux installations, no issues with themes, icons, Xorg config; in practice - take fraction of flatpak storage size, optional sandboxing with external tools like firejail, easier to run from terminal / dmenu / rofi, very easy to tinker with and fix.
There's just one problem: they don't integrate with desktop without an additional application. We need a feature where dropping an AppImage into "~/.local/share/applications" would automatically detect it as a ".desktop" file and make it appear in the DE menus.
