Sever blessing, shatter enchantment outcome

[leftside]

I tend to mash these buttons when they light up, but often struggle to figure out what they removed.

Is there an add-on or some Buffhead setting that can determine the outcome?

Afaik fist to come first go. So basic buffs like zealot marks, sorc buffs, shaman resist buff and so on

Thanks for that---but is there no add-on out there that will, for example, tell you that 'your shatter removed [some buff]'?
