Forum:Reference popups

What would be everybody's opinions on having a reimplementation of Wikipedia's reference popups; the feature that lets you hover over a citation and displays the contents of the reference in a floating box. The obvious advantage of this is that you can view the references in situ without having to scroll to the bottom, or click the citation and lose your [mental] place in the article? ~ Ultimate  Supreme  12:44, December 26, 2012 (UTC)
