This first license is for the documentation only; the Sugar CE codebase is licensed under the AGPL.
Besides adding desktop icons, introducing Thunar (en lieu of xffm) and MousePad, applications that are as simple as effective, Terminal that has built-in support for desktop composition (which is supported by the window manager out-of-the-box), it also introduced (finally!!) shortcut for the pop-up menu (you can see in the tour that Ctrl-Esc is binded to this menu)!!.
Congratulations for the lightest and slickest window manager ever:)"
