Old Style Group Window?
 

I just downloaded your UI and I love almost all of it...
I have looked through the forums and seen that you provided help to people who didn't love one part of it or another and I used that to fix my inventory window size.

My question is, I really preferred that horizontal group window, I spread it across the top of my screen right beside my name so i could just easily go through everyone.
Your window is vertically oriented and I cannot figure out how to change the size or the orientation if it. Is there a way to make this window horizontal instead of a vertical box?

In the ProfitUI Updater go to Settings>Varients and then go to the dropdown and change it to Group. From there you have a variety of choices including changing it from Vertical (default) to Horizontal.
