Comment on Coollris Previews

I make extensive use of the popups tool on Wikipedia, so I tried this extension on Windows. I actually found it to be kind of annoying and a bit slow after the novelty wore off. The big problem for me was inadvertantly launching previews, this could be avoided by only showing a preview when a certain key is pressed.

Something a little more lo-fi a la Wikipedia would be nice. I think this concept could eventually be done quite well.
