I built this and had ion load this module successfully, however none of my wmdock apps (nor bbslit apps) appeared in the dock. I didn't change anything from the default dock.lua.
Which wmdock apps are you using? If you tell me then I can download their sourcecode, understand how they implement dockapping, and possibly add support.
alt+space doesn't appear to do anything, either.
This will only have an effect if there are apps in the dock. If there's nothing in the dock then it is effectively size zero and you'll never see it.
Cheers,
Tom
