For confused first-time visitors and other people still acclimating, here is a description of these little tabs to the left, as well as some other features of the site.

Settings are saved per browser tab, so they will be remembered for your whole visit.
Open My Eyes - Have you ever been engrossed in your work, when you suddenly realize someone is staring at your screen, watching everything you do over your shoulder? If not, this simulates the experience.
Open Help - This help popup, silly! You just clicked it! Do you not remember?
New - Draggable elements!

Positions are remembered per tab, so as you navigate around the site, they will stay in the same place for your whole visit.
Enjoy!
