Move "Hide from Site Drawer" closer to work area in Preferences > Sites

Our users use this area incorrectly all the time - every day - because it sort of mimics the old way we used to hide or favorite sites in Sakai.

Users never notice the "Hide from Site Drawer" header over the list of sites, and they always think that, by checking them in this list, they are adding them to their site banner.

a) nobody knows that the actual *Sites * button will open something called a Sites Drawer. That term may not be the most intuitive.
b) the header of Hide from Site Drawer is separated pretty significantly by space and the instructions box so they literally NEVER realize that they are hiding sites from themselves.

Can we move the header down to just above the area? Maybe a confirmation message can explain that this does not affect student visibility. Or a message at the bottom of the screen next to the Update Preferences button.

I am open to any suggestions regarding usability for this process.
