*Swing timer. This is quite a heavy feature (requires listening to the very busy combat log events), and i think it is more suitable for an independent addon.
How much CPU usage would this use if you were to implement it? Really like this castbar, but as a hunter it would be convenient to have a swing timer aswell. Maybe as a plugin or a lua option (so casual users wouldn't accidentaly enable it and suffer a slight performance decrease).
