Weakaura show you all spells used by near players. Its very helpful in the mythic keystones when you need to know if (for example) warrior use shockwave or healer his cooldown. It's also tracking lust efects, so you don't need addons for tracking who lusted. If you want edit, add or delete some spells it's very easy. Just go to Trigger -> Custom Trigger -> Expand (in the bracket is spell ID).
This weakaura is not made by me, unfortunately I can't remember after 4 years of using who made it. I'd love to give credits if you let me know.

It should work in the Shadowlands without any problems.
