+modes. Either mode can be applied dynamically, optimizing the environment for

 .P
 In tiling mode windows are managed in a master and stacking column. The master
-column contains the window which needs most attention at a time, whereas the
-stacking column contains all other windows in a stack.  Dialog windows are
-managed floating, however. In floating mode windows can be resized and moved

-Windows are grouped by tags. All windows with a specific tag can be viewed at a
-time. But each window may contain more than one tag, which makes it visible in
