I can't change the angle of the rule or shapes to the exact angle where i need it, it goes from 149 to 151, and i need 150. THAT REALLY MESSES UP WITH MY LINES. Also it is super important to have a solid plain square that doesn't have angle twists. Ive been already 3 hours to do something that could have taken half an hour on photoshop. But photoshop for iPad, is well... lets not get in there.
