What do you want to see next?

I just remembered a problem I came across for visual comparisons - I can't compare first run with second run (with primed cache) of the same page.

My use-case is obvious - to see how caching affects the speed of rendering.

It would probably be also meaningful to allow to compare two cached versions of different pages (e.g. dev vs. production) too.

I hope it's easy to do - it looks like images are already collected (filmstrips are different for them) and it's just a matter of providing the user interface.
