Hi!
I recently bumped into Paint.NET, and I really love it, great job guys!
The one thing I missed was gradients, but I D/Ld the plugin, and voilá, i have gradients.
But since I use it for pixel painting, I have one more features in mind (as far as I can remember, I haven't encountered it in any other painter)
1) Step-Gradient: you specify Color A and Color B, and the number of colors you'd like to see in the gradient. This would be a great help, since pixel graphics look good this way, and you wouldn't have to fiddle with the colors between A and B.
Plus I'd love to see the integration of gradients into the painting tools (like gradient filled circle, etc.)
Thanks for this great software!
