Is there any manual for this app. There are a lot of settings and no explanations other than the limited FAQ. I want to know - how to set this reader so that when the app is opened it automatically goes to the last page that I read in the current book I am reading - without having to set a bookmark each time I close the app. ALSO - how do I make all text in the book bold? I read ebooks due to a slight visual impairment so that I can make text larger and need to make the text darker - or bold. I see the settings for text - but no way to indicate a bold font for all text on the book pages.
