Oh wow, it's been 4 years since I've been here (time sure flies by) and now there's paint.net 4 (coincidence? ). I hope this post is alright, but I'm really happy you guys are still working on this software. I really prefer it over Photoshop and GIMP (ugh, I really hate that one tho).
Looking at the feature list, I'm surprised there's so much new stuff (here I thought paint.net is already stuffed with great features).
