Hi!
I use oUF included in my LUI unitframes and I love it.
Although, I wish it did one thing that it doesn't appear to do, and that is, I need the player names inside the unitframes (as opposed to the bars or the icons, or even the corner indicators), to glow when they have a certain buff. In my case it would be Eternal Flame, but I'm guessing this would be a useful feature for everyone!
I was sent here by some friends in the official Battle.net forums, so I hope this gets some consideration!

Thanks!

oUF does not do anything by itself, it is up to the layout to implement features like the one you demand. You have to ask the creators of LUI to implement this for you or do it yourself (in that case I would suggest using the wowinterface.com forums for help)

What Rainrider says is true. You'll have to take this up with the developers of LUI.
