Why isn't there a button that I can click on that takes me to the previous page? For instance, often I click on a link that takes me somewhere else in my epub magazine. There should be a button I can click on to take me back to the previous page I was on. Calibre as well as other epub readers have this feature and it is great! Please add this as it is very frustrating.
Also I just want to say thanks as this is the best epub viewer I have found when it comes to annotation. Keep up the good work! I would love to be able to use this program as the one and only app for epubs in the future!
