I'm looking for a plugin that I can use in the following scenario:
- I export my Calibre library (not the books, only the data stored at Calibre database) and send it to my friend.
- She imports that library as a separate book-less library. Then she starts working on fixing the tags, genres, etc.
- Once she is ready with fixing, she exports the library and sends it back to me.
- When I get the library and importing the differences to my existing library. The plugin prompts me with changes and I accept them (or deny some of them) and the merging happens.
- The books with changed metadata are marked in Calibre so that I can work on them (embed metadata, etc.)
I know this sounds complicated and does seem niche, but isn't that what plugins are for? I hope someone finds the idea challenging enough to give it a shot.
