This has been a long time coming.
I think we first discussed this in April 2007.

Can you characterize what changes to the core (if any) were required to
support this?

> +--
> +-- If the type can't be infered from the usage of the retrieved data, you

> +--
> +-- > .. getState :: X ListStorage

> +-- >
> +-- > instance ExtensionClass ListStorage where
> +-- >   initialValue = ListStorage []
> +-- >   extensionType = PersistentExtension
> +--
> +-- Additionally, you have to instruct the user to add a type witness to

> +-- can use undefined, since it is only used as a type witness:
> +--
> +-- > myModuleExtension = PersistentState (initialValue :: ListStorage)

> +-- > .. stateExtensions = [otherExtensions, myModuleExtension]
> +--
> +-- One should take care that the string representation of the chosen type
> +-- is unique among the stored values, otherwise it will be overwritten.
> +-- Normally these values contain fully qualified module names when deriving Typeable, so
> +-- name collisions should not be a problem in most cases.

>  Currently, the ppUrgent method is an addition to the ppHidden method.
>  This doesn't make any sense since it is in fact possible to get urgent
>  windows on the current and visible screens. So I've raised the ppUrgent
>  printer to be above ppCurrent/ppVisible and dropped its dependency on
>  ppHidden.
>  
>  In addition to that this makes it a lot more easier to define a more
>  custom ppUrgent printer, since you don't have to "undo" the ppHidden
>  printer anymore. This also basicly removes the need for dzenStrip,
>  although I just changed the description.
