Thanks, I'll read through this and try to figure it out when I get a chance (maybe later today). In the meantime I get a compile error:

jefdaj@acro:~/.xmonad$ ghc --make OnlyFor.hs
[1 of 1] Compiling XMonad.Layout.OnlyFor ( OnlyFor.hs, OnlyFor.o )
OnlyFor.hs:60:64:
    `m' is applied to too many type arguments
    In the type signature for `onlyFor':
      onlyFor :: HowMany
                 -> m -> l a -> ModifiedLayout (OnlyFor (m a)) l a

If I comment out the type signature and load it in GHCI it guesses this:

onlyFor
  :: HowMany
     -> m
     -> l a
     -> XMonad.Layout.LayoutModifier.ModifiedLayout (OnlyFor m) l a

Does that look reasonable? m is One | Multiple, l is the LayoutModifier and a is the Layout right?

I've attached the current version; it compiles but is not tested in practice.  It should be clear enough how to extend it to support other values than One and Multiple.

Except I forgot to actually attach it...
