Improvement of the EPUB format interface.
It would be great if the EPUB format interface can be changed to be as similar as possible as the most common ebook interface that the majority of ebooks in EBC has got. An example is to have the table of contents to the left.
The current interface for EPUB ebooks is not so easy to understand when the reader is used to the more common one.
We also think, when setting the downloads to 0 for an EPUB ebook, (due to the current covid-19 we want to do that, so that as many users as possible can read it without delay), a different message than the current error message is needed. Instead of "There was an error.." we suggest a message that is more adequate, like: "This ebook is not downloadable. Please change to online reading." And, of course, if we omit the 0 downloads setting, the message will not appear at all.
