[D-Brox]

plus some small fixes and QoL improvements

[D-Brox]

To be discussed: When Flatpak (regular/beta channel) is enabled, give the user an option to install flatseal from flathub?

https://flathub.org/apps/com.github.tchx84.Flatseal - Flatseal is an application used to manage flatpak permissions.
