Hybrid library view

Hi,

Sometimes I miss the covers in book list view, so I wonder if there's some way to create a custom column to display (not exactly store) a cover thumbnail. This is an illustration I made after adding 40px extra spacing between rows:

One of my wishes for Calibre 8 would be this 'hybrid' library navigation mode, a combination of cover grid and book list.

(the resized column icons to fit the extra row width don't look nice at all but i could live with it)
