Enable infinite scroll on front page?

I’m experimenting with masonry-powerd themes; and Gridz is looking good.

One thing I would like is infinite scrolling on my front page – currently Gridz shows 10 posts only. I’ve installed the infinite scroll plugin, but I’m not sure how to get it to work with the Gridz front page.

Another thing: does Gridz support Masonry “brick size”? I have a post for which the brick size is set at 1×2, but it just takes up its usual 1×1 size in its column.

Anyhoo… thanks!
