@alatiera That'd be awesome. However:
GitButler is Tauri*, not Electron, so that makes it trickier (for now).

There are at least 2 Tauri apps that are in Flathub already, but Tauri 1.x doesn't really support it well. Tauri 2.0 should support it soon?
* Tauri is basically like Electron, but uses the system webview to make apps a lot smaller. (On Linux and macOS, that means WebKit. On Windows, it's the Edge version of Chromium, IIRC.)
