For example, I’m using Debian, and I think we could learn a thing or two from Mint about how to make it “friendlier” for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be “the universal operating system”.
I also think we could learn website design from… looks at notes …everyone else.
Please read my reply before you repeat. How should the different versions of an application be handled? What if the shortname is already taken? There will be collisions, which the longname tries to solve. Flatpak is not a repository where all names can be checked against, this is the job of a repository like Flathub. What about different versions of an application?
This is not a simple case of forcing to specify shortnames.
