Comparing to the previous version a large amount of work has been made. User comments and suggestions were taken into account: the text navigation was simplified, new convenient contents and reading history were added. Added possibility to bookmark any arbitrary position in the book. Removed bulky and unnecessary interface elements and performed many other nice modifications.
Application includes full user's manual which is not includede into application anymore (saving user space) and can be downloaded separately on demand.
The list of currently available books is not final, as new books will be added from time to time.
