I like the new light style.
But I’m still waiting for a GUI space reducing. To make long story short – here is my Nautilus mockup: http://nureineidee.files.wordpress.com/2010/03/nautilus-lucid-lynx-2-mockup.png

Space usage of my idea: http://nureineidee.files.wordpress.com/2010/03/nautilus-lucid-lynx-3-mockup.png
Space usage of the current Lucid Nautilus: http://nureineidee.files.wordpress.com/2010/03/nautilus-lucid-lynx-1.png

Key idea: Reduce GUI element space and obtain functionality. When mouseover an folder after 0,5 sec folder information should be shown – like it is in Lucid for the system menu right now.

Thats all – Keep on going, your aiming in the right direction.
