Good afternoon,
I am having difficulty finding the scroll button in the positioning strip on the right side of the full-screen viewer. (I am fairly certain my nomenclature is incorrect but I hope someone can make some sense out of this description.) Is it possible to change the color of that button either by some change in the program or via a plugin? I am of some knowledge Calibre wise, but I am still trying to understand what is going on ePub and Calibre wise. I am working through some CSS and Javascript, but I have a very long way to go. I did manage to make some changes to the CSS of the viewer for my computer, so I am at least familiar with that.
Thanks for your time and attention to this matter.
