Yay, someone who actually likes the Unity interface! :P
But yeah, I get your point. Ubuntu did a great job of conserving screen space with the Unity launcher. Only thing is, I can’t see how it applies to web dev. You would need an icon for each page instead of a name, correct? And for those with mobile devices, they can’t hover over the icon to see the description.
Not saying its a bad idea, just wondering what your ideas for putting it into a site layout are. ;)
