Yes, but the selection at the place I referred to does it permanently for you, regardless of any session info saved in the cookie. So if you set it the way I recommend, and you log in with a different browser and/or on a different system (like your iPad or phone or the system in your observatory) you still get the default style you want.

I see the auto-save, but I'm not sure how to get back to the auto-saved state if you get cut off. I haven't tested it though. I have my hands REALLY FULL right now, hence I am here on Sunday.
