On: Will This Be The New Google Web Design?

[ErrantX]

I've had some split tests of this hit me (I think) over the last few weeks.

On my netbook it hid the sidebar (I think this was deliberate and not a split)

I've also had it appearing/disappearing by default on various desktop machines (I think that was a split).

I have to confess it is growing on my as a feature. The icons convinced me to start using the filters and some of them are useful.
