Hi Norbert,

I'm not aware of anything in contrib addressing your first point. But
adding it should be fairly straightforward, considering you can
define:

doShiftScreen :: ScreenId -> ManageHook
doShiftScreen screenId = flip whenJust doShift =<< liftX
(screenWorkspace screenId) -- fairly sure this typechecks

And then use it exactly as you would use doShift.

This kind of thing might fit better in XMonad.Hooks.ManageHelpers than
in DynamicHooks.
