I love Paint.NET and I use it all the time, I've got a lot of plugins but I would need 1 effect that is present on The Gimp 2.2, called Supernova the fact is that I use the gimp only for this effect, I don't need anything else from that software, and I would be much better if I could use the Supernova without having to change programm everytime.
Here is the screenshot of the effect:
I hope you make it
