Add Floating support, crop issue

Can you make this a floating app? As it will greately be functional because you do not neead to download the image before being process. 

Can we not crop the image? I mean i dont want to crop the image that i want to ocr. I just want the image as is coz i dont want to edit the image and make it larger so that it needs to be cropped.

Sorry english is not my first language.
