Inline structure mode

There is an excellent field plugin for dynamic managing of page contents, the builder plugin.
I tried to migrate one of my projects to use this great plugin, but for me this solution lacks of one requirement.

Contents for the page often have their own (more or less complex) structure fields!

Because the pages contents are edited in a panel popup, there can no other structure be handled.
So what do you think about a third style option ‘inline’ for the structure group, which could be enforced by the builder plugin?
I think about an entry list, which contains all fields for each element of the structure displayed as the defined input field type. So the contents are written and managed direct in the structure list without opening a popup.

Generally, structure fields should work without the modals, then we would not have this problem in the first place, I think. :+1:
