Allows to have several floating scratchpads running different applications. Bind a key to namedScratchpadSpawnAction. Pressing it will spawn configured application, or bring it to the current workspace if it already exists. Pressing the key with the application on the current workspace will send it to a hidden workspace called NSP.

If you already have a workspace called NSP, it will use that. NSP will also appear in xmobar and dzen status bars. You can tweak your dynamicLog settings to filter it out if you like.

Create named scratchpads configuration in your xmonad.hs like this:

 import XMonad.StackSet as W
 import XMonad.ManageHook
 import XMonad.Util.NamedScratchpad

 scratchpads = [
 -- run htop in xterm, find it by title, use default geometry
     NS "htop" "xterm -e htop" (title =? "htop") Nothing ,
 -- run stardict, find it by class name, place the window
 -- 1/6 of screen width from the left, 1/6 of screen height
 -- from the top, 2/3 of screen width by 2/3 of screen height
     NS "stardict" "stardict" (className =? "Stardict")
         (Just $ W.RationalRect (1/6) (1/6) (2/3) (2/3))
 ]

Add keybindings:

  , ((modMask x .|. controlMask .|. shiftMask, xK_t), namedScratchpadAction scratchpads "htop")
  , ((modMask x .|. controlMask .|. shiftMask, xK_s), namedScratchpadAction scratchpads "stardict")

... and a manage hook:

  , manageHook = namedScratchpadManageHook scratchpads
