You did a great job with this addon, and I'm about to transition from vuhdo!

One feature I would like to extend the raid debuff section is a sold color option.
I like the glow options for the raid debuffs. This works well for short debuffs.
Additionally I suggest a solid color option, i.e. color the frame "red" when a specific debuff is on the player.
I personally did this on vuhdo for longer duration debuffs which require steady heal but no immediate action.

I don't know of it's easy to implement or not. I would love to see it.
Thank you in advance
