This could probably be lumped into "PowerClip Editing Contents" by Ruben, but I view it a little differently.
Cropping is really nothing more than supplying a clipping mask and then removing the "masked area" The function already exists. We use it when we set a custom product decoration area. Essentially, what I am looking for is the ability to select a clipping mask and supply a background from stock images or uploaded images. The "masked area" would be below subsequently added text or images allowing for "layers" of decoration.
I am not asking for a custom clipping mask, just a basic circle and rectangle that can be sized without regard to proportion. This would allow for most "cropping" functions.
The primary application is photographs where we want to drop out a background or select one idividual in a goup photo, etc.
The next step would be to place the mask image behind the "cropped" image with a 4 or 6 pt stroke and apply a gausian blur to feather the edges into a white or black border, so it doesn't look so much like a "cut-out".
The obvious advantage is to allow a retail customer to upload and crop an image as part of their decoration without having to involve the "art department". If it could be treated as a design image element, it would allow for it to be a "chargeable" feature much like adding a custom piece of art from a pay as you go source.
Alternatively, if it would be possible to upload a template to accomplish this, but that would be limiting.
