It's called an opinion, and I think it is superior to that mess. It features most of the common tools you'd need for more common things, however I will admit it doesn't have the everything and the kitchen sink feature list of GIMP or something like Photoshop. Still it's free, feature-rich, getting better, and much easier to work with than the messy GIMP. To each his own.

Also, it's aimed at anyone interested in photo editing or drawing, etc. It's not a natural painting specific application like Dogwaffle (which is also a great program I recommend esp. for that natural aspect).
