Smart snapping for Upfront elements?

I'd love to see improved snapping for Upfront elements so we can quickly align blocks relative to each other. I can count columns to make sure something is centered, but the grid is too dense vertically to do the math on every element.

Here's a jfiddle demo of what i'm talking about. Would save lots of time!
