Seriously though, why there is no shape tool in Gimp?

Because it’s a UX mess.

Because creative FOSS is usually terrible, their methods demolish the flow of an average creative worker with constant "No, it doesn’t work like that "-type interruptions.

Intuitive functionality is never a priority and never done right. If anything it seems to be viewed as sacriliege to sacrifice clean and simple code for the base instincts of an ignorant user.

I remember finding some comments from people being pissed that Blender got an Undo function. Felt like I was living in a bizarro world.
