Personally, I like about 20 or more props added to the bases. So in order of what I want:
1: Prop Doors: About five kinds of doors that are just props like in the Office and Warehouse missions. 5 to 7 of these would make the make bases feel bigger as well as make them more immersive.
2: Prop Windows: Again, about 5 different kinds of windows in the style of what is in the universities, but with couple different shapes and tints. It be nice to have something other than the Eye of Doom winds.
3: Beds: Having th beds with out the straps and other kinky stuff would be real nice.
