Finished reworking the research sheets. That was the biggest pain so I wanted it out of the way.
Sins uses 8 - 1024x1024 TGA sheets for all the abilities and research buttons. Each are 4mb
Buttons_Research_CursorOver.tga
Buttons_Research_Disabled.tga
Buttons_Research_Normal.tga
Buttons_Research_Pressed.tga
Buttons_Research2_CursorOver.tga
Buttons_Research2_Disabled.tga
Buttons_Research2_Normal.tga
Buttons_Research2_Pressed.tga
After tearing the sheets apart and moving the buttons to the appropriate sheets I have a Shared-Research that will be used by all the races and will be placed in the base m0d. 1024x1024 TGA 4mb

Now I have a 1024x1024 TGA sheet for each race that will be placed in the add-on for that race. Here is a look at the TEC-Research which also has room for all the TEC Rebellion buttons or added to for Diplomacy.

This means I can enable 6 more races of research sheets just to be on par with the original UI and each races sheet is completely customizable.
