I assume they are going to make some changes w/ the HUD for retail... smaller font's, smaller icons, etc... In the mean time, I made some changes myself to clean the screen up... there's a lot of info on there you don't need. Here's what I did:
This clears up the entire bottom of the screen and perhaps most importantly eliminates the big yellow circle/orb things that show where the current CP's are. Hopefully they'll shrink the font for enemy names and squad member names like they did with hat... but if they don't, I'll probably turn off squad list too.
