Are there any alternatives to the jQuery endless scrolling plugin?

I couldn't find one that did exactly what I wanted so I built one from scratch. It has a pause feature so it doesn't keep loading endlessly as you scroll. Sometimes somebody might want to see the page footer. It simply appends a "Show More" button to continue appending. I also incorporated localStorage so when a user clicks away they won't lose their place in the results.

It also has a callback function that can be called to manipulate the newly appended results.
