A grid view of book covers

calibre now has an optional "grid" view of covers, a convenient way to judge the books in your collection by their covers :) To turn it on, use the button with the icon of a grid on it in the bottom right corner of the main window.

In the finest calibre tradition the view is highly customizable, you can adjust the cover size, the space between covers, choose to display the book title below the covers and even change the background color! All the customization is available via Preferences->Look & feel->Cover grid. See the screen shots below.
