-- WorkspaceDir is an exstension to set the current directory in a workspace.
--
-- Actually, it sets the current directory in a layout, since there's no way I
-- know of to attach a behavior to a workspace. This means that any terminals
-- (or other programs) pulled up in that workspace (with that layout) will
-- execute in that working directory. Sort of handy, I think.
