I can no longer see the incoming (predicted) healing on my target frame.

I've tried changing all settings to reflect those in my Player frame which is working fine (background alpha, incoming healing settings all identical) but no luck.

Really great addon regardless :)

After doing some more testing, the target frame only shows incoming heals if they are in your party, or you're targeting yourself.

So if I'm healing a random player out in the world, I can't see my inc heals on them.

Is there a way to change this?

No, because you can't see their hp and thus can't know how much your heal will heal.
