OSX El Capitan Folder Quick Look Redesign

This is just a mockup of a feature I'd love to see in El Capitan. Quick look preview of folders in finder, with comments/annotations.
In the current OSX UI, Quick Look for folders just displays folder size and a large folder icon that takes up valuable space that can display more important information.

Not to take anything away from the awesome work that Apple designers do, This is just my take on a feature that I would like to see.
