Instead of placing windows all over the screen, the windowing manager, Con10uum, uses a linear paradigm, with multi-touch used to navigate between and arrange the windows. An area at the right side of the touch screen brings up a global context menu, and a similar strip at the left side brings up application-specific menus. An open source community preview of the Con10uum window manager was made available in November, 2009.
