Any ideas on what simple features that could be added to this Offline application? JavaScript only [on hold]

This application works offline, it stores food inside a database, and the details on each food, such as servings, and calories, it's a work in progress. So i want to add a few more final touches to this application, a few features that are JavaScript related only, any suggestions.
