What did you think of the changes between Paint XP and modern versions? I used to adore Paint XP, but brush smoothing (though toggleable) and a clunky interface really spoiled the newer versions for me, and I don't enjoy using them as much. I think I just became so used to the primitive way of drawing well in the old versions that it sort of became it's own art form. Now they there are more advanced tools and so many required extra clicks, it feels like baggage. In the words of Karl Havoc, "THERE'S TOO MUCH FUCKIN' SHIT ON ME!"
Honestly, I never used Paint XP. I've only used the modern version.
