I dont want just squares ;-;

Ive read a lot of reviews of people saying that they have to give the app five stars in order to get a cool feature, but I genuinely like this app. Its really cool, and comes in handy! Theres only one problem, however. I want to make pictures that arent squares (like a short width but a long length), but there isnt a template that you can do that with. I want 5x7 and such, not just a square. Im trying to make book covers and I cant because theyre all SQUARES.
