SUMMARY It would be nice if in System Settings/Default Applications the user could choose their preferred/default application store. The chosen program would open .deb, .rpm, .flatpakref files and appstream:// URIs. It would also be launched when clicking on "Uninstall or Manage Add-ons..." in the Application Launcher (kickoff). As an example, let's say the user has installed the Bazaar app store and would like to use it instead of Discover. This feature would make this feel more 'accepted' by the system.
