paintnetking

I have been thinking that the shapes are too limited (too few) and searched the web if I could create my own or something. I found that there are "packs" for that. And I have to manually download and extract the files into C:\Program Files\paint.net\Shapes , which is not fun. Isn't this kind of dumb? Why do users have to do this manually? Can't the shape show something like [Install more] and show the list of user-contributed plugins for shapes and install them right there?
