文書を見るアプリとしては最高だが

いつからか残念なテキスト表示が追加された。その頁のメモだと思うが頁をめくりちょっとでもタッチが長いとポンポンと顔だす。こんなラクガキを見たいんじゃないだ。あろうことかこのメモを表示したまま頁を移動可能だ。さらに最初の頁を超えて本棚まで戻れ不動となりアプリ削除することになります。削除し再度インストールこと何十回か。もし戻れるならテキスト表示がなかったバージョンに戻りたい。せめて設定でオンオフ機能が欲しい。以前の
このバクが復活したので評価は1です。

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.
