You can currently set it so you can see some things no matter what if there on your screen using sight. I request some sort of sight list that I can add atoms to that can also be seen no matter what. It would also be nice if something where like the invisibility and see_invisible except instead of see_invisible being equal to or greater then invisibility to see it...It instead has to be equal to see the other atom.
There are plenty of cases where this would be very useful.
An alternative method might be to list what you can't see instead of what you can see.
