Link page to side note on Note 2? backup including side notes?

Had this feature in Note (though it was taken down on one of the version of neoreader then returned as an optional feature), but absent in Note 2. Not understanding the back and forth that onyx is having with this feature. Also, having lost all my sidenotes when my Note broke, is there any way to backup PDF/epub including sidenotes then restore with sidenote in correct position? Thanks

The sidenote will not be linked to the page in the Note2 and the latest firmware now.

Our R&D team is working on this feature now, and users could only export the sidenotes and then backup via 3-rd party Apps or other ways separately.
