The automatic background removal option is really neat! And I love the URL - great to have a utility one click away when I want to jump into an idea. Congrats!
Fantastic set-making tool. One-click background remove is a very smart and useful feature which I've always needed.
A very pleasant surprise was the 'tidy-up' feature. I never knew I needed it but it does an excellent job at making order out of chaos and gives you a great starting point for your set.
