I find myself reading on a Kindle Paperwhite, a Samsung phone, a Samsung S8 Ultra tablet, and a Boox Nova Air.

Sometimes I'll start a book on one device, and then totally forget where in my syncthing synchronized directory (same place on all devices) where the book was.

Is there a way I could piggyback on my existing syncthing directory to synchronize some part of the koreader directory (files/folders there) using a tool like syncthing / rsync / unison etc?

Synchronize the history list across each device. I.e. open a new file on one device, all other devices would receive this information and my history screen on any device would be the same.

Synchronize the annotations, notes and bookmarks from device to device. i.e. I highlight a passage on one book, then all other devices receive this data. Would be super handy.
Many thanks for reading this.
