GIMP is missing such basic, basic features and things, that I genuinely wonder what's going on with the development or how anyone uses it for anything other than basic editing. It's nice that it's free and open though I guess.
Not saying this is technically basic, but it's a basic need for anyone doing print.
How "basic" are these is debatable though. They are very useful, and widely used, and multiple image tools support them, that's for sure.
