Kitty Cat Theme – Smaller Version for smaller resolution screens.
More themes at:
This theme works better on:
*) 16:10 and 16:9 aspect ratio displays.
*) Higher resolution displays. (ex: 1440×900, 1366×768, 1280×800, 1024×768, etc.)
Anyway you can try holding Ctrl key and using "+" or "-" keys to zoom in or out on new tab page. This will change the image scale and maybe you'll find a nice view to your likes.
