title: Is it possible to animate extension popup opening?
body: <p>I developed a simple chrome extension. Following the answers in this SO <a href="https://stackoverflow.com/questions/5544256/how-to-programmatically-open-a-chrome-extension-popup-window-from-background-htm">post</a> I was able to programmatically open the popup window on certain webpages. The default behavior of the popup is to open a window at the top right. Is it possible to modify this behavior? Ideally, I would like the popup window to slide in from the right after the automatic <code>window.open</code> is invoked in the background script.</p>
