I love this plugin, thanks a lot!
What would it make even better for me, would be and x- and y-coordinate field for every of the 4 corners where I can set the exact values, where I want them to be.
Like this, fine tuning would be much easier and more exact.
I mean something like the fields we have in rotate for the 3 axes, but of course for Distort This there would be 8 such fields (2 for each corner)
