The UI for Sins is a thing of beauty and wonder. Except for all of the wasted real estate. There is soooo much wasted that I just had to do something. And since I can't yet mod features via scripting (Come on Ironclad, patch that in for us!) well, here we are.
This is just a simple UI mod, I changed a .tga file to get rid of all that metal and altered some XY coords in two .window files to tighten things up and viola! We're done. The mod SERIOUSLY adds in some extra "roominess" all the way around, so hopefully people will like it.
Here is what the final output looks like:

I've posted it to the upload site and am waiting for them to approve it, but for now you can download it from here:
LazySumo's MinimalSimply drag the folder inside the .zip file into your Sins folder, backup your install and run the RUNME.bat file by double clicking. Please read the file before you run it, it simply renames 2 files and copies 2 files. CHECK IT FIRST SO YOU KNOW.
Enjoy playing Sins with the extra screen. The visuals ingame are so pretty, I can't believe they decided to hide so much of it.

I've changed the mod to be a complete UI minimalization, previously it was only the bottom bar, but I really like the way it looks now.
