Sub Areas in Area

Permalink
Hello.

I'm trying to add the ability to change the location of the areas on the fly using the visual interface of the pre-prepared layouts set. For example, the location of the blocks in the header, footer, or that any special markup for content.

After several days of searching and reading the source code, I found two options:
1. The standard grid layout
This option is not approached because it allows you to add only one cell line and makes it impossible to control the display of cells on different devices (xs, sm, md, lg classes for bootstrap)
2. The new block type with different templates include an sub areas. (Concrete\Core\Area\SubArea)
This option is very similar to what I need, but it gives management an sub area and blocks in them becomes very difficult or even impossible (hover working incorrect).

Perhaps there are still some options? Or maybe I'm moving in the wrong direction, and there is an option easier?

I would be grateful for any help
