What you're describing is pretty easy to do with cookies, however I'd prefer this data to be stored online in a database table, so that it would only have to be set once for a particular user. I think this sort of stuff goes along with having a more unified user login system (I shouldn't be able to modify another person's settings, etc) and as such isn't really what I'm focused on right now.
Right now, I'm currently trying to get the general function and design of the pages down, and will probably be able to push to the main repo by the end of the week.
