I was wondering if it would be worth considering adding the ability to limit how many rows can be added to a grid layout? We are using nested content in a lot of cases mainly (or only) because we couldn't limit how much content could get put into 1 grid field. We have templates were we want to give our content creators some flexibility in layout, but only in a particular section, however we wouldn't want them to add a lot of content to that section, just a row or 2.
