Request for Feature - Validate Pointers to Books
Recently, the Calibre e-book manager project has been beta-testing MTP-drivers which will allow users to directly add and delete books on their devices from within Calibre. Already, people have complained that deleting books on their device does not delete from the Mantano book-list. I realize that this is because Mantano requires the user to import individual books rather than relying on a scan of one or more directories, so Mantano has no way of detecting that a book has been deleted from outside of Mantano.
I would like to suggest that Mantano add a menu option to validate the pointers to the books in it's book-list. Mantano would simply run through all of the books in it's list, checking that each book actually exists. If a book does not exist, it should be flagged in some way, perhaps by a tag or adding it to a "Missing Books" collection. From there, the user can decide what to do with the entry in the book-list.
