These should have been standard options in a game like UT3. Actually, some of these things are so ridiculously redundant that they never should have existed in the first place (ie: Vehicle names that pop up when you enter them are an example that comes to mind. I can clearly see which vehicle I entered - as a matter of fact, you could tell even if the vehicle was invisible). Just how dumb does Epic thing the average gamer is today?

In-Game User Manual (HUD text instructions telling you how to play the game)
weapon and vehicle 'pickup' names
middle-screen death message
white arrows
billboards over players
shine-thru-the-map node signs
player VOIP portraits
HUD 'doll'
crosshair changing with each weapon
crosshair color changing when you damage someone (bugged anyway)
crosshair "growing" when you pick up stuff
Glowskins (remove or at least ability to adjust)
and we need;
custom crosshairs
option to scale down HUD size
sorta related, the ability to scroll view when in vehicles
And there just might be more I forgot. I'll be watching for fixes through Epic or mutators and share with you if I find them. Please do the same if you see something. Or maybe something I have listed actually can be turned off? If so, please correct me.
Edit: Here is a mild example of what I'm calling the In-Game User Manual;

None of those text messages should be there. Or at the very least, allow them to be turned off. Each of them you should already know, or are redundant because you're already being shown in the mini-map. You should know how to play, and you should know the map.
One possible exception - with the current HUD - is the one telling you are carrying the orb. Obviously in 3rd person (on the hoverboard) you don't need the message, but in first person maybe you do. But that's only because with the current HUD, you can tell your orb is being carried, but they could improve it so that you could tell if it was you or not. And do away with the in-game user manual.
And again, that's a mild example. If we really tried, we could come up with an actual in-game screenshot that is practically filled with instructions (text or otherwise).
