I mean, there are already tons of applications that lets you e.g. update, like apt update/upgrade does.
One issue with it is that it fails time to time, and error messages the GUI usually conveys are subpar. That’s why I think you cannot avoid terminals. I just want some middle ground for that.
Also, ik this is nitpicking but… while apt is good on this front… what about the CLIs whose --help gives hundreds of lines?
