Being able to disable people using the eye "following" button on you.

There should be an option that you can select that will make it so people can't follow you when they hit the eye button and unchecking it will make it go back to normal. I'm sure there are a lot of people who want to be able to draw in their secluded part of the map and not having random people "eyeing" them, some of which can be potential griefers (which happened to me today).
