The threat warning sound is great for dps so they know to back off when their threat gets close to the tanks.

I suggest having a similar warning so that when you're tanking and someone else's threat gets to 90% of yours, a warning sounds. Preferably a different warning to the 90% threat warning for dps players.

Old comment is old, but...  I believe the threat API is target-limited, so you could only provide threat warnings on boss fights, not trash pulls, which IMO (as a perennial tank) are the times I need some sort of threat help.  There must be some other sort of means of getting threat on multiple mobs, because my raid frames (Stuf & Healbot) do it, but it might be beyond the scope of the current Skada codebase.  *shrug*
