I haven't found a mod that does this, so I'm making a request - all the messages in New Vegas, such as ones relating to Reputation gains/losses - can they be moved to the upper left hand corner instead?

I think Fallout 3 had a mod that did this. Basically, any message that requires user input and stops the game flow - like DLC added messages, or "PRIMM SLIM HAS DIED!!11one" messages - move them to the upper left. Simple, and makes the game a whole lot less intrusive.

If there is a simple way to do this, teach a man to fish and I will gladly apply it to all the messages myself.

I would like to know where these faction status message boxes are as well. I can't see them in the geck anywhere and they really disrupt the flow of gameplay.
