Autoshot Fail warning?

[Zario]

Hey all, anyone ever seen an add-on that warns you when you clipped an autoshot with my own movement?  I'd like to start making the shift to MM spec which is heavily dependent on your autoshot physical damage, and I need to get better at my movements.  I use Quartz right now, so I have the timer, but it's hard to pay attention to it when boss fights get hectic.

Thoughts or suggestions?
