I have 2 questions about epub 1st I just got a galaxy tab 8.9 and it has ebooks on it witch reads epub files great but one thing I can figure out is this had had an iPad before the tab and in any epub book if I were to click a link to take me to another page in the book and once I clicked it at the bottom left would be another link to take me back to the previous page I was on but I don't see that in ebooks if it exist can someone tell me where its at? And if it doesn't exist what's a good program to download that reads epub files?
