At the request of its users, Adobe is working to make the iPad version of its Photoshop app a bit more useful. The latest feature it's getting is the Refine Edge Tool, which helps select or crop objects with more complex edges (like curly hair, animal fur, etc.). The company tweaked the interface a bit for the iPad, but it supposedly works similarly to the desktop counterpart.
Aside from getting Refine Edge, Photoshop for iPad now has a two-finger rotation gesture, allowing you to rotate and zoom in on the canvas simultaneously. The rotation can snap at 0, 90, 180, 270 degrees, but it's possible to switch off both snapping and rotation itself in settings.
