Thank you sleepyDragon for your answer.
What about the use of the dictionaries? A person said for example that English dictionary hasn't worked good reading a English epub. Do they work normally? Even if I search for a inflection? (like "goes", "gone", "dogs" -> and the possibility to read the meanings of "to go" and "dog")
If you can upload pictures it would be great.
