XMonad.Layout.CenteredIfSingle

A layout modifier that, if there is only a single window on screen, places that window in the center of the screen. This is especially useful on wide screen setups, where the window would otherwise be unnecessarily far away from the center of your field of vision.

Usage

You can use this module by including the following in your ~/.xmonad/xmonad.hs:

import XMonad.Layout.CenteredIfSingle

and adding the centeredIfSingle layoutmodifier to your layouts.

myLayoutHook = centeredIfSingle 0.7 0.8 Grid ||| ...

For more information on configuring your layouts see XMonad.Doc.Extending.
