Hi,
I was trying to automate some sleep/wake actions and found out that there's only "before mac goes to sleep" related trigger. I think, I was able to achieve what I needed but how about adding a few more power-related events like "when mac wakes up", "when AC power connected/disconnected", "On login/logout", "When battery charge reaches a certain level" (upwards/downwards).
Not sure if these will be widely used - just some ideas.
Cheers,
