@pyrochild, I downloaded the beta, and thought I'd give you a feedback. I noticed it is faster and smooth when smudging. Even though I have used Smudge a lot, I never realized the hidden power of "Smoothness" until I played with it, and I liked it a lot.
Is there any way you could add a visible clue to inform users there is an ability to add background color? It seem it is accessible only by right-clicking in the interface window, which was something I figured out by accident, and I saw your discussion between Sarkut and yourself.
It also took me a couple attempts to add a new brush to the palette, if you will, and I think it's because I didn't read through the first post, and didn't see a "Ok" or "Cancel" button on the bottom of the browsing window. Is this remediable?
Thanks for all the hard work, pryo!
