So, you made a change to your dashboard, and now you have to run all over the building, plugging in a keyboard, and reloading the dashboard on the various TVs in your office. What if you could reload all the dashboard from the comfort of your desk?
Add this widget to the very bottom of your dashboard, after the "gridster" div:
<div class="gridster">
<ul>
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
<div data-view="Image" data-image="/benbria/loop.png" style="background-color:#666766"></div>
</li>
