Small player, target, implied..?
 

Although my dream UI would look like this, I am willing to settle for something that already exists.

Is it possible to use ONLY the player, target, and implied target windows from ProfitUI?

I tried just copying & pasting those three windows into my UI folder, but they just looked broken.

How can I make this work?

Thanks in advance!

When you're copying them, you have to make sure that you copy all image files and other files that are associated with them. If it's missing image and font files, that's probably why it looks broken.

What I'd do is do things the opposite of how you're doing them now: Copy the UI files you want to change into a ProfitUI install (or, if you're going for default, delete the UI files you want to change and it'll load them directly from default).
