-                Это клон читалки Omni Reader, но с некоторыми дополнениями, ориентированными в сторону более свободного обмена книгами:
-
-                <ul>
-                    <li>добавлено новое окно "Библиотека" для свободного доступа к Флибусте и другим ресурсам по желанию читателя</li>
-                    <li>планируется добавить возможность создания подборок книг и обмена ими между пользователями</li>
-                </ul>

-                Легко мигрировать на новый сайт можно с помощью синхронизации с сервером.
