I bought Acorn shortly after it came out because it gave me a really easy way to snag application icons for Tagamac. Sadly, it didn’t have any web export features, and when I upgraded to Leopard the resizing starting sucking hard core (lots of black artifacts).
Enter Acorn 1.1 which includes web export, resizing bugfixes, and much more. Now perhaps I won’t have to launch Photoshop every time I want to stick some stupid image online, which was really what I was looking for when I bought Acorn in the first place. W00t!
