A Feature that i would like to see, and i know its still early days and in beta, is compatibility with windows 7 features. in particular aero peak. similar to IE8 in windows 7, make paint.net jobs so they show up as different windows, like tabs in IE8. i think they do this by making each tab a different task.
i hope it makes sense :?
Like this: (you can look without actually go into that window ((Peek)))
