Feature request: cache book list
Its very inconvenient that every time application rescans all books from scratch. It does not remember list of files. And worst part: it does not scan books metadata at all, so book can be found by search only by file name (only when book comes visible at file list its metadata are scanned, and only then it can be found by name of book).
That makes application practically unusable on large collections. It should cache scanned data.
