LIbrary - covers on folders?

In Yac reader library, Navigating the folders is cool, but I'd like to have them look more like the main view - or to integrate it completely.

The idea would be you would look at a list of folders - but instead of being a list, it would be a cover from the comics in that folders. Maybe it would autoselect the first, but you could edit which comic cover to display in an advanced options?

Then you click on the folder and it will open up the main view with covers as well.
