Addon that will display boss HP as a % in separate window

[Azrok]

I'm looking for an addon that will pop up an extra window or health bar that show's the boss health as a % rather than a number. I know you can change the default raid frames to just show health as a %, but I am a raid leader and healer and need to be able to see boss % for things like

-Nefarian (electrocute every 10%)
-Chimaeron (phase 2 starts @ 20-22%)
-Maloriak (similar to Chimaeron

etc.

I don't have the boss targetted during fights, and setting him as my focus will still only display health as a number

Any addons that just show boss health % that I can put next to my Grid?

DBM can and does do this for Boss fights. the box/bar is moveable, though you have to tick the box for it.

DBM does have that features, but you need to activate it on each boss

I use TargetHealthPercentage its super light and easy to config but ull have to target the boss.
Its adds a little black box-thingy u can place it wherever u want.

Most UF addons will add a boss hp bar which can be configured separately from other bars to show % hp. If you don't use a UF you could even download a simple and lightweight one like Shadowed UnitFrames and disable everything except the boss thing and just use it for that.

Thank you all! Went with the DBM option
