Enable the built-in PDF reader to recognize annotations (notes, highlights, etc.) made in external PDF readers (such as Acrobat and Evince).
The built-in PDF reader do not recognize annotations (notes, highlights, etc.) made in external PDF readers (such as Acrobat Reader and Evince). The problem is twofold:
(1) when I include notes on Mendeley, I must export the notes as a new PDF file, so they cannot e changed in another PDF reader; and
(2) when I include notes on my Android device (with any PDF reader), the notes are not recognized by Mendeley.
My suggestion is to enable the Mendeley's built-in PDF reader to recognize such annotations. So the changes made both on my tablet (external reader) or on my desktop (built-in) are compatible.

Implementation idea: For synchronizing to the server split PDF-Documents into an immutable core document and the annotation part. Unless the file is edited rather than annotated this should be possible.
This would allow synchronizing the base document only once and store it only once for all users (as presumably happening now) and synchronize / store per user only the annotation part.
On systems were third party software may access the documents, the annotated pdf would have to be written at sensible times (e.g. when closing the document in mendeley after performing annotations) and parsed everytime a change occurred from outside Mendeley (e.g. when the last-modified time doesn't match the time recorded in Mendeley).
In between the current proprietary format can be used as kind of a cache. In particular on iOS, where app data is entirely inaccessible to other apps unless explicitly sent to another app, merging of base document and annotations into a standard annotated PDF would be needed only when using "Send To" and splitting only when another App sends a PDF.
Third party clients would require a server-side splitting of uploaded pdfs and merging before download, though not providing this (probably costly) capability simply would keep the situation unchanged with regard to Android clients.
For those not using the official Mendeley software for annotations: I'd recommend placing the PDFs in a separate cloud storage directory and NOT to let Mendeley synchronize the attachments. It is a loss of convenience, but none that currently can be helped.

This is really important. Please let Mendeley to recognize annotations made in other PDF readers and make annotations made in Mendeley to be readable in other PDF reader.
Alexander Hirner commented
Not adhering to the standards is a substantial design flow and moreover inconvenient. This issue dates back 2 years (1) and I see no movement. At least a rationale of why to double bubble the annotation system at first hand and and a statement of the developers regarding the concrete feature request of the OP is appropriate.

Yes...it is incredible that this is not possible already....

I'm in the same boat - floating somewhere between using Mendeley for new articles I'm reading, and storing everything else in Papers because I can't import my annotations. It's the biggest thing keeping me from finally ditching Papers and embracing Mendeley. Please make it happen soon!
Dan Levenstein commented
I would also like to be able to migrate my annotations from Papers to Mendeley - was in the process of switching due to the fiasco that is Papers 3, but this may be a deal breaker as I would lose a few years worth of highlights/annotations/etc.
Bryan Kutner commented
I'd like to see the same thing, to enable migrating files from Papers to Mendeley. I've imported PDFs from Papers using the RIS export/import, but I don't see a way to import the annotations along with the PDFs.
Daniel Speek commented
Is there any current Windows PDF reader which recognizes the annotations that are made in Mendeley?
