There should be a tab in the user preferences to allow users to have a second set of settings to be used when logged in via a mobile device. Things like handheld.css (mobile.css) and handheld.js (mobile.js) should be accessible from there as well as being able to set the number of days and number of edits to view to a much lower number than what they view on the desktop site to reduce load times on much slower (sometimes) mobile devices. There should also be the ability to disable javascript/jquery for mobile devices on the page. You could have a checkbox for whether or not to load images for the user on their mobile device, whether or not to use beta/dragons modes. Also, some kind of reset mobile device settings without messing with other settings. Allow for a different signature for editing from mobile devices to let others know that little typos or whatnot are more likely as a result of using a tiny keyboard than editor error. Just some ideas that I think would make a great separate tab in my preferences.
