Is there a WM that is more customizable than gnome but you do not need to configure from the scratch?

Last weekend I installed awesome WM and I really think this name is a fair one, this WM is really awesome. I liked how it felt efficient and customizable. I did not do anything special but I had the feeling I could be very efficient using it. After some hours tweaking it (theming, some keyboard shortcuts and things like this), I found out that many "basic" things was not provided out of the box:

• Multiple screen support (one should use arand to configure it and then import in the rc file)
• My keyboard screen brightness keys should be configured
• My keyboard media control keys were not configured
• A shutdown button in the ui And probably some other things that I did not have time to find out (I don't understand why Gnome is able to provide it out of the box and awesome WM is not).

I would not like to invest my time setting up things that are already provided somewhere else, therefore I ask: is there any WM that provides you more of-the-shelve basic features, but allow you more customization options than gnome? Something between awesome WM and gnome?

Thanks!
