Why does "Clean Up" remove all reading states? I have to remember all of them now since I clicked the button without knowing what it did, and there's no documentation for it in
https://github.com/baskerville/plato.../0.8.4...0.8.5. I had assumed that it would remove all reading states and database information for books that were no longer present in the library, for example the Wallabag folder that I had just made its own library.
