MobileFrontend currently loads all sections on a page, but hides all of them right away. Instead of loading every section whether they're going to be used or not, the sections could be loaded using Ajax whenever the section is needed.

Since this would also need to work for when a user clicks on a link to an anchor, this would require an API module that could be given an ID of an element, and return the ID of the surrounding section along with the complete contents of the section.
