At first glance

This app looks great on the surface, but there a few key factors were missing here to make this a dual development platform. First, the ability to control both views with one inspector. Changing CSS in one doesnt affect the other. Second is user agents. Without the ability to change them, the left pane is nothing more than a smaller window.

The promise here is much greater than the delivery. Hope you guys have more planned, because Im $5 down and back to flipping tabs in Chrome.
