Enlightenment is a window manager for the X11 windowing system. Its design goal is to be as configurable as possible - in look AND in feel.
Fast. Beautiful. Completely unlike others, and especially unlike other 'lightweight' WM. And fast. unobtrusive. Now with compositing, shadows and all that, splendid.
I always love Enlightenment since the 16 version , and 17 looking very nice :) i wonder if it has tabbing like fluxbox i might switch to E17 if it does :P
Great! Way above the others! I use it for <a href="http://www.carinsurancecomparison.com/" target="_blank">car insurance quotes</a> and it works great!
