We have been trying to work with the OneDrive Program Manager to get Bookmarking added. So far they don't seem to be able to wrap it's head around it's importance, so let's list the Office 365 users in business, academia and elsewhere who would benefit from having Bookmarking in OneDrive eliminating the need for a 3rd party annotation tool, which is a non-starter if you use Intune MAM as we do. The beneficiaries would be anyone who works a lot with PDFs, with the bigger the document the more important bookmarking is including: lawyers; anyone who has to review a contract; market; sales; research analysts; researchers; professors; students, etc. Considering an annotation module to annotate PDF files in the OneDrive for iOS app exist, how much time would it take to add bookmarking, if the tool can already tag and search for annotations.
