I'd like to see a new crop overlay to help with layout on Instagram. Instagram's grid shows square thumbnails cropped from landscape and portrait images. A cropping overlay that displays a square the full length of the shortest side of a rectangle would be very helpful.
Sorry if I wasn't clear.. I'm talking about overlay. I'd like to be able to choose any crop ratio (particularly 4x5) and see a crop overlay of a centered square that extends to max dimensions. Some of the different overlays currently include a centered square by chance but they are small squares and I'm looking for a square that extends from side to side. It's quite common for websites to generate thumbnails by cropping images square and this could be useful for a various applications.
