That being said I can imagine if KDE didn’t have Kate or Konsole or any of that - there’s plenty of text editors and Terminals that already exist out there.
i gotta join in with the other Linux Mint voices here. It’s very user friendly. You just need to know:
the desktop environment is called Cinnamon. this will help you google stuff.
the system package manager is called APT, and if you just use the update manager you won’t have to interact with it directly, but it’s good to know.
in the software center many apps have the options sytem package or flatpak. system package means it goes through APT, flatpak is a sandbox system that is good for isolating your apps from your system. imo always choose flatpak, except for steam.
