How can another addon register to the swing timer reset?
Is it possible to use this as an API or just dependency to get the swing timer resets?

I'm not 100% certain how to hook together add-ons or develop APIs for add-ons.
That said, as long as you change the enabled setting on all the bars to false, the background logic should still run but the visuals will be hidden.

I realized the swing reset was actually just SWING_DAMAGE MISS SPELL events so I incorporated that.

thank you
