It should be possible to control hat placement algorithmically.
Why is there only an option to modify hat placement with a mouse? It would be nice if we could also resize, move and rotate our hats without using a mouse.
Using a mouse can be difficult; you're trying to move the position, yet suddenly the size of item starts changing, and there's no easy way to change it back. It would be nice if we had other ways to access the hat controls; for example, with the keyboard, via input fields.
