By the way, I went to the KiCad downloads page () and found that they have 311 downloads for Windows (either native .exe or .zip) - no "flathub" required. The MacOS section has 95 downloads (all native .dmg files) - no "flathub" required. Yet there are no downloadable versions for Linux. They either rely on the distribution's package manager (apt, dnf, pacman, pkg, emerge, or zypper) or they require use of "flathub". Why not just post the flatpak images directly?
