Crop rectangle the same ratio as focus rectangle

I gotta tell you, I am loving this module. However, one question…unless I'm not understanding correctly how this is supposed to work (I've only been using this for a day or so now).

But shouldn't the crop rectangle maintain the same width x height ratio as what is set for the focus rectangle? Or can you at least allow an option for this? It seems like that would make sense, but like I said, I may not be understanding the intent of the crop rectangle.

Note: the crop rectangle comes in at the correct ratio; but when resizing the rectangle the ratio is not locked.

Thanks, and great work!
