LeRayonVertThis is beautiful. 10/10 would use if you make it 4:3 compatible.
Things that will not work in 4:3 would be loadout/backpack stuff (and apparently closed captions), the rest of the hud should work without (m)any problems, I'll have a look at it in 1024*768 and 1280*1024 before I release this into the wild.
But with the way the hud is set up it should be really easy to make your own changes without losing these when you update the hud (which is done by simply extracting the default hudfiles!)
