That's a really interesting idea - showing information about hidden element. Thanks for the pull request.

I wonder if it might be an idea to group all hidden element events into a single array which is then output at the end of the Visual Event run, rather than potentially flooding the console with warnings.

Indeed, this could be extended to show a bit more information about what Visual Event has found (the summary information for example).

Actually idea is borrowed from DOM Monster https://github.com/madrobby/dom-monster - it reports detailed info in console
