In the app called Documents, by Readdle, there is a feature for PDF files called Crop Mode, which removes excess white space around a page (if applicable), allowing text to be brought more to the front, closer to filling up the entire screen. It is very functional, and makes reading easier since the texts is expanded. As you can see based on photos, the text becomes significantly bigger. This feature alone makes me have to keep my textbooks in the Documents app, since GoodNotes doesn't have this feature. Would love to see it come to GoodNotes! Thank you for your amazing work thus far!
