@__tosh Thanks for the question!
While basic PDF functionality inside PDF Viewer will always remain free, we have plans to launch premium subscription-based features and services over the next year, such as the ability to create digital signatures, page text editing and others.
Probably our most exciting premium feature coming in the near future is our real-time collaborative sync solution. This will allow anybody that's a part of a team or with friends to annotate a document in real time whether online or offline. We really think this will change the way people collaborate on PDF documents similar to the way Google Docs has revolutionized word processing.
Again, the PDF functionality included today will remain free and we hope to provide valuable add on subscription services in the future.
@fdorfbauer Yes, we automatically save the annotations you create in PDF Viewer and you can see them in any app that conforms to the PDF standard.
For bookmarks, there is no standard, however we went the extra mile so that bookmarks created in PDF Viewer are compatible with Preview on macOS - check out our post on it here - https://pspdfkit.com/blog/2016/j...
