Thank you very much for this. I’ve tested it with my rather large KoReader library that I use Syncthing to sync between multiple devices. Just pointed the plugin at the Sync folder, and setup the destination for the notes. Worked just as needed, and now I can read on other devices, click one button, and know the things I’ve highlighted will be captured/noted in Obsidian for later combination with other notes.
I’m fine with separate files vs one big file, since I don’t think the management of updating notes in the file is going to ever be a “nice” experience, my idea is to just link these extracted notes from other actual notes with my thoughts (and combine multiple together if I need to).
