Hello, I have been working with Paint.net a lot recently, but I have found a minor problem that bugs me a bit sometimes. Currently, when working with the line tool you only have 4 "nodes" to play around with to change the shape. I included a demonstration of a program called Pinta, which lets you freely adjust the amount of these nodes whenever and wherever. Thanks!
P.S.: Maybe an option to choose between pre-generated nodes and this?
