A few more additions.

This would be a perfect Photoshop replacement if it just had a few more additions. It would nice to see a "Feather" and "Color Match" feature added, that would make blending images and layers a lot easier, while there is a Hue feature that can be hard to match colors on images sometimes.

An auto blend feature would really make this easy to use. If those features are there, I couldn't find them.
