Nice change, thanks.
Add extra viewport to default set

The gap between Smartphone Landscape and Tablet landscape is too large, and you can't add a new one inbetween.
I'm proposing adding a Tablet landscape roughly halfway between. This gets a decent coverage in the default set (and makes it more useful for sending pages around for review)
