Own files

Yes, it can save my file to it but, one by one. There is no copy and paste to since its local library cannot be read. When I used open in. It just put one file in it when I selected more than 2 books. Hoping getting easy to get around my own files.

Everything is great. Shelfs and reading. Thank you.

Two page

Please add "two page view" in portrait mode too.

Broken updates

The app changed some setting I assume for iOS 26 compatibility but now the text for the titles of the books is huge. Not sure what they did but the app is broke.

Test your updates!

テキスト表示にバグがあり

本棚画面でテキスト表示になり固まって何もできなくなります。
こうなるとアンインストールし再度インストールする羽目になります。
これはテキスト表示のバグだと思われます。
やり方
インストール後初期設定のまま、本を開きますがここでは例としてStandRackGateを開きます。
何ページでもいいですが長押ししテキスト表示をします。
そのまま長押ししたまま上半分画面の枠左から右へスライドします。
テキスト表示されたまま画面が本棚です。

Works Amazing
