Safari's missing feature: expose

I have strange internet habits which lead to a considerable accumulations of tabs that I've opened in the background, because I think they're interesting.
As such, my windows often get quite full of tabs.

Expose within the Safari window would be a fantastic way of visualising all of these. Safari tabs are the only things which are not shown by the otherwise omnishowing expose.

Change this!

 

EEEEEE happy です ^^
but will it work...
And I can é my expos- si tu veux
