I’d like to suggest replacing the current native Linux package with a Flatpak version (or at least providing a Flatpak as the default/preferred distribution format).

Flatpak is a universal packaging system for Linux that allows applications to run in a sandboxed environment across virtually all major distributions (such as Ubuntu, Fedora, Arch, etc.). It ensures consistency, security, and ease of installation for users.

Why Flatpak could be a better option for Gupax:

1. Cross-distribution compatibility: No need to maintain separate packages for each Linux distro. One Flatpak works everywhere.
2. Simpler updates: Users get automatic updates via Flathub, and devs don’t need to manage multiple release channels.
3. Better security: Flatpaks run in isolated environments, reducing the risk of system-level issues.
4. Popular distribution method: Many modern Linux users expect and prefer Flatpak (especially from Flathub), which simplifies app discovery and onboarding.

Please consider switching to Flatpak or at least making it the default recommendation for Linux users. I'd be happy to help or test a Flatpak version if needed. Thanks for your great work on Gupax!
