For those of us who use tablets, we often scroll pages with a thumb along one side or the other. Often the margin of the page on the "thumb" side is too narrow and instead, a link or photo is accidentally touched and the page veers quickly off to content the user had no intention of seeing. It's annoying. Perhaps you could add a configuration option that concatenates the widths of both the right and left margins together to create a wider scrolling space on the chosen side. The option to select either the right or left side for left or right-handed viewers would help.
