Link from personal to group library? Group library annotation?
Apologies if this has already been discussed, as I couldn't find it. I have an item in the group library which I want to annotate for myself only using the new builtin PDF reader. I could copy it over and annotate, but this would duplicate storage. Is there a way to create attachment links from my personal library to the group library, so I may then have private annotations? Moreover, is group library annotation (can be messy, can be powerful) a planned feature in the future?
