Good for basics.

Can you please add a feature to manually skew individual corners for when an image just needs a small adjustment from the film plane being slightly off from the subject? I shoot lots of 2-D flat rectangular items on a basic surface (photo frames, signage, etc) with my iPhone and sometimes just need to just tweak two opposite edges slightly in one way or another and dont want to go all the way into Photoshop to do it. Also, please add the ability to turn a grid on and off.

Thank you
