Starting this summer, the Local Bookshelf and the Trunkroom Bookshelf are merging and book management will be simplified.
As a general rule, the Trunkroom Bookshelf folder will continue to be available.
If you wish to continue using the Local bookshelf folder, please use the tool prepared to copy it to the Trunkroom bookshelf.
Please copy the folder from [settings] > [bookshelf setting] > [copy bookshelf folder name to trunkroom]
(translator note: the app itself has been translated, so the setting names above are how you will find them in the app.)
