Add option to save URL to allow back button functionality

[ghost]

When a user navigates away from an endless scroll page it would be nice to be able to save the URL of the last loaded page so that they can click the 'Back' button and resume browsing from where they left off, without having to scroll all the way from the top again. I think this would be really effective, if it's possible, with this plugin since it allows for both appending and prepending elements. So instead of having to load all pages up to the the one the user last browsed, you can just load the last browsed page and from there either append or prepend pages depending on whether the user scrolls up or down.

Is this something possible to do with this plugin?
Thanks for an awesome plugin
