I would love brushes in Paint.NET, but this is exactly the reason I didn't create a topic about it. But the GIMP and Photoshop both have brushes (heck, even KidPix has brushes) so why not Paint.NET?
The two most annoying things that is not in paint.net are:
A bevel effect
Brush Styles
However, I would also like more custimizable gradients (like being able to use mroe than 2 colors)
I know C# (at least a little beyond the basics) but It has been confising to me because I can't do anything related to graphics or drawing. Especially making a plug-in for Paint.Net. This tutorial clarified a lot of things for me, but probably not enough for me to accually make a plug-in.
This is a GREAT plug-in, but sometimes the blur is a little too much, I don't know if this has been suggested or not but if its possible, maybe you could just anti-alias the hard edges instead of accually bluring them. This would be even better!
Finally! A border plug-in. Thanks so much Madjik! I've been waiting a long time for one of these. I did find a bug: If you try to add a border to a circle, it turns out as a square with the corners cut off.
