I really like jharker's proposal.
Just a minor comment: imo fullscreen should go on "page" submenu, and should be activated by default when opening new docs.
Also, I can't get the desktops idea for the iLiad.
As most of our apps/docs should be opened maximized, which are the differences between changing desktop to show other contents and minimize current app and maximize next in the apps/docs ring? why to waste bottom buttons for a not-so-useful-feature-in-iliad?
My hot dreams include a tiled wm like awesome [1]... don't know if it is posible or even interesting for people.
Best regards,
Iņigo
