Short description May be we can add similiar to the WikiConfigHelp macro one which can list the available actions. It can show the action name, the doc string and it's state of actions_excluded of the current wiki settings.
The classification of listed action can be derivated from the naming scheme, e.g. lowercase written means not listed in the actions menue. The meaning maybe can be derivated from the name itselfs and the imports it does.
If actions can be only called by a special user e.g. superuser then the description could be hidden from the normal user
