A button to straighten a scanned document would be so useful, particularly for anyone using a document feeder to scan. Currently, if you go to edit the document, it will straighten the pages for you, but it will sometimes convert handwritten notes into a font and change their appearance, which isn't ideal for signatures, for example. So, a separate option to straighten the document would be life changing for me at work.
Please add the votes here to the Deskew feature request. They are looking for the same thing.
I think there is already such a feature in Acrobat DC.
In Scan & OCR, click Enhance/Scanned Document. It adjusts without OCRing.
Add it to the Quick Tools area for easier access.
It would be nice to have more control by degree as someone else has suggested
