It's important to be able to export my annotated pdfs, especially for sharing w/ collaborators. Please also implement this on the iOS version
Definitely need to have some way to share my annotated PDFs. The 30-day free trial may work for some but most of my collaborators won't buy a subscription and our timelines are longer than 30 days.
When I send a collaborator a paper I always tell them to just read the highlighted sections so this is a great inconvenience for me.
