One thing I do miss from ZorinOS is packages not being up-to-date. I think it would be nice to have some of these packages that are frequently installed, or asked about, much better updated through the official repositories.
For example, in this other thread @Aravisian found that flameshot is no longer available on the official Ubuntu repositories.
@337harvey also suggsted Python and Nodejs, two pacakges that while available (and Python is even pre-installed) are not even remotely up to date.
Other programs such as Brave browser are also not available through official repositories at all, although to be fair I don't think this is the case of any distribution for some reason.
I'm not saying that every package should be tracked and updated, or even to the very latest version, but having packages that are over 5 years out of date is very disappointing.
