The Desktop Divider facility allows sub-dividing either the entire large desktop or each monitor in a multi-monitor system into several adjacent non-intersecting areas - tiles. Each tile then can be filled with a window: just begin to drag it - and you will see the grid indicating the current tile layout. Drag the window to any border of the desired tile - and the window will span the tile's area.
Such approach makes utilizing the screen real estate in a most efficient and ergonomic manner: arranging the windows within the tiles will cover the entire visible area with no gaps and overlaps, thus letting you observe all windows easily at a glimpse. In some sense, Desktop Divider provides benefits similar to Windows 8 Modern UI but you can get those benefits on any OS and with any application.

Desktop Divider allows you to do the following:
create a layout with various number of tiles of different sizes
create as many layouts with various tile configurations as you need
assign a custom hotkey combination to a certain layout to activate it instantly
switch between layouts using the Desktop context menu
switch between layouts by scrolling the mouse wheel either while dragging a window or over tile selector
put a window into a certain tile of the current layout
stretch a window over several adjacent tiles of the current layout
