I like how it has its own library, which BTW does not need to copy into a separate library, like iBooks. I think it has some chinks in its armor, and have written the developer, but no response yet. I'm going back and forth right now between Clearview and Murasaki Pro, and might just use both of them without making this some kind of a contest.
My hopes are that, since it has a browser feel, it would be able to have a hot-key to shift between tabs. It can be clunky to load up sometimes, but hasn't crashed. It has a good text search engine in reading mode, and the library function can search for title, author. I can edit the book metadata if needed, I was using Murasaki Free for research papers, and it'd been accepted so far for citation.
Good app - just wish the developer would respond. 我也用中文给他写信。。。
