Flatten

The flatten feature allows you to embed annotations, form fields, and other interactive elements directly into the content of a PDF. This process converts these elements into regular, non-interactive content. Flattening can be useful for ensuring that your PDF looks the same on all devices and for preventing further modifications to form fields and annotations. Details here.

Orientate and Deskew

The orientate and deskew button found on the Page Controls toolbar allows you to easily tidy scanned pages. It will straighten the pages in the PDF and adjust the orientation where required eg portrait to landscape. This means you don't have to spend the time rotating the pages yourself.
