You're very welcome, but I'm just trying to figure out what is wrong there, so please, bear with me.
First of all, I don't know how it looks on your screen, but it looks like this on mine:

Buttons are big?
How come these buttons are big? Compared to what? I actually enlarged them to 24 because the default size of 16 was too small for the game screen height of 1440px. Now the size is 1/60-th of the screen height.
A lot of buttons?
Yes, a few more than default, but they're taking less space because back, skip and auto buttons are compacted to a few characters max and Q.Save and Q.Load are now just Q.S and Q.L. There are only 2 buttons added to the default configuration: Load and hide UI (on the far right).
Split instead of the middle?
Yes, I tried to make the UI less intrusive than Ren'Py's default and as transparent as possible to cover less of the background image, without losing much of its visibility or functionality. The idea behind splitting buttons to game play related buttons on the right (back, skip, auto, hide UI) and all other buttons on the left (History, Save, Load, Q.S, Q.L, Prefs) is to cover less of the central area of the background image where usually the focus of most scenes is located and move buttons to the corners of the screen.
If this is not your cup of tea and you want your buttons smack in the middle of the image, then sorry. Right now this is what you get from me.
It may become more flexible in the future though.
