Distribute Linux app as a flatpak
It is no question that Linux users love choice, and some of the best distributions do not easily support .deb or .rpm packages. Namely, Gentoo, Arch, Void, NixOS, and Clear Linux. These are all unique distros that I like to use, and they all use various packaging methods. Luckily, flatpak is supported on all of them (see https://flatpak.org/setup/).
Please add flatpak as a package format for the Linux client, whether it is the current command-line version or a future GUI version. This would be incredibly helpful for so many users that use distributions other than Debian, Ubuntu, Mint, or Fedora. And for those that do use those distros, flatpak works natively on them too, so it's a win-win for everyone!
