At any time, you can add, change or remove annotations giving you complete control of fluid projects.
Annotation Summary Page and Count
You can make it easier for your friends and co-workers to review all your PDF annotations by appending an Annotation Summary page as the first page of the PDF you plan to share.
In the Annotation Summary page, cropped areas show precisely where on a page each annotation appears.
Finally, Evernote provides an Annotation count, which is a running count of the number of times each type of annotation is used in a document.
Both the Annotation Summary and Annotation Count is optional. You can use them whenever you find useful.
