Action Tracker

I think it would be great for something like an action economy bar to be used during combat. Nothing that would actually limit actions, as even after it "fills up" it wouldn't stop you, but it would help a GM make sure someone isn't doing too much in a round. You could maybe program most of the common actions, like attacking, full-attack, charging, spellcasting, and move actions into the system, and add to the abilities a selection of what type of action an ability is.

Who knows, maybe if you expand the item, feat, and spell capabilities, you could even make them apply abilities like haste to the action economy bar.
