Hi, i love the simplicity of your addon. But for my taste it could use some customization options.
The major issue i have is with focus frame. I use Prat 3.0 for my chat. When trying to set a focus target i get Prat 3.0 error and focus doesn't appear until i disable Prat. As a tank i kinda need focus target :)

About customizations - moving frames would be fantastic, and if you want to stick with your design, at least give us "tick" options like "lower unit frame position". "Hide when out of combat" is a must. Would also love to see hp numbers converted into Millions.

I'm unsure why Prat 3.0 is causing that error and honestly it's far too big of an addon for me to go digging in to attempt to figure out why. This UI is the only addon I have installed (why it was created) so I don't go out of my way to support external addons.

The positioning configuration is definitely something that is on my todo list with an issue open #43 I haven't managed to pencil in the time to get stuck into this yet but it will get done eventually.

Hiding the frames when out of combat was something the addon did back in early WoD or late MoP and I remember having to remove it due to taint but I can't seem to find the specific commit. I'll have a look at this as I would like it as an option myself.

HP numbers conversion i'm not going to touch since Blizzard are doing another stat squish in BfA.

Going to close this and point at #51 instead. The Prat issue may or may not be fixed with the new re-write but if not I won't be going out of my way to support it.
