This is so good! It lets you crop, gives you lots of control, has the "oops!"/undo button that THANKFULLY can undo an accidental "obliterate" because I absolutely had a panic when my mouse suddenly jerked over it (my fault.)
And in the options you can change colour scheme AND if it's meant to be transparent, which kind of gives you a fourth colour to work with, too.
and, while not bad, it may do to note for others that the markers and mask all go under the black tools above them. But the eraser does handle both at the same time on mask/transparent mode!
