The plan for this feature is to open a separate Dark Energy sheet on the witch's character sheet that displays the total in a small separate window. Actors can be given permission to use an actor's dark energy by being given a specific 0-cost general feat that contains a link to the actor's unique ID. When opening the spell-cast dialog, if there is an energy cost, check whether the actor has dark energy or access to another actor's pool and show a dropdown option for whether or not to use it.
Functionality has been added in Release 0.14.12. The Witch must be set with Owner permissions for all players in order for them to apply the energy pool updates (#52)
