Ok, I guess in theory, a split screen function can come in handy at times. The problem with this add-on is that there are no instructions, turning it off is next to impossible, and they placed the switch in absolutely the wrong place. Put it on the toolbar somewhere; don't hide it on the scroll bar. I can't tell you how many times I would start scrolling, and the window would just split; I didn't even realize what I had done the first few times. And undoing it is too big of a hassle.
I uninstalled it.
