1 patch for repository http://code.haskell.org/XMonadContrib: Sun Aug 19 12:11:07 EDT 2012 allbery.b@gmail.com * XMonad.Layout.OnlyFor This layout modifier allows another layout modifier to be applied only when a single window or only when multiple windows are visible. (The case where no windows are visible is vacuous since layouts are irrelevant.) Rough usage: import XMonad.Layout.OnlyFor, then use as a layout modifier myLayouts = OnlyFor Multiple (Spacing 3) $ Tall ||| Mirror Tall ||| Full gives you a Spacing 3 modifier unless there is only one window visible. This has been sitting around in my local tree for about a year, after I wrote it for someone on #xmonad; it has vanished from hpaste since then and I never got around to submitting it to -contrib.
