> Uninstalling an application would mean just deleting all the objects in its package. The files would be gone and any configuration settings with them.

Applications developers of the world. Please always make "keep configuration" an option with your uninstallers! I don't like the mobilification of PCs. For example, because of some issues, I wanted to try a different version of Thunderbird. I had the Snap version. Uninstalling it meant losing all its mails. I wasn't expecting that. Like at all!
