/*
 * The aim of this project is to provide more features
 * to the DAKboard. The DAK board is an amazing wifi connected wall 
 * display for your photos, calendar, news and weather.

 * Yup, I'm cheating. My project is not really an extension.
 * I am just finding a way to switch chromium tabs or application
 * with an external hardware. Keybord in the mean time.
