The "app" is just a bit of jquery that hides/shows divs based on their classes. It skips a refresh if the filter is empty ( to avoid creating an invalid jquery selector?), so if you set "View Partials" to "Yes" and then "No", nothing changes. Anyways, I just forked it and fixed it.

This is a simple little app, but it's a good example of how using the DOM as a model and a view (as most jquery apps do) doesn't create the most elegant code.
