Crop Pages as a standalone icon
When you need to quickly crop a page it's irritating to have to go to EDIT and have to wait for it to recognize the text/language of the content on the document before you can select CROP. Often the text doesn't need to be edited, you just want to get rid of the white space.
Cropping should be it's own icon/feature separate from other "editing" functions so that it's fast and easy.
Also, the idea someone posted for combining two small crops into one page is excellent.
