How about a "you draw the crop shape" option. You might draw a skinny crooked rectangle through a picture to crop off a corner or a person or a triangle or a lopsided circle but you could jig and jag all you want or need so that it gets rid of what you don't want more easily. Some programs have this feature and it is most helpful if a uniformed crop is too ....uniform. Sounds to me like it would fit "scrapping" nicely with jigs and jags and wiggles.
I know this sounds like something shapes could do and that works for some things but it slows you down to have to go make a shape to fit your crop need. I usually need two shapes to get the job done and haven't figured that one out yet. Is there a way?
BTW...love the program.
