How cool would it be if you could create a page layout in the DnD builder, then save that as a template.
This functionality is already (mostly) in the Email builder side of things. I would love to be able to port that same functionality to the Web and Landing page side of things.
This would streamline the process of creating templates, to the point where you would almost never need to write a line of HuBL if you didn't want to.
Reusable sections would be another incredible feature here. Rather than building those sections in hubl, if we could "right click > save resuable section" that would be amazing.
