I have just bought the Marvin full version on my ipad Air and so far I am far from happy.

1 Multiple downloads from Dropbox only pick up 2 books. By the time you have pushed all the buttons you could have downloaded each book individually faster.
2 When I read a book I would like to know how many pages there are left in the book but I only get a percentage number and a meaningless figure of number of pages in the current section whatever that is.
3 My ebooks come from calibre and carry tags, which are rather important to me. In Marvin I cannot sort my ebooks by tag and can't even see which of my books have been read. Marvellous! An earlier version of Marvin had this option.
4 Instead of getting your books nicely listed in the library you get your books shown with fancy labels that take up so much room that you get 6 books per page spread over dozens of pages. I don't want it pretty and inconvenient, like Apple, but concise and useful. Asking too much?
I get ebooks on my Galaxy tablet via calibre companion, Simple and convenient.
Cheers
