I think it would be a great if you could use your mouse-wheel to control the azimuth
of your guns. One 'click' on the wheel = one degree.

Can't even imagine how helpful this would be. You get your fast 'TDA' like
adjustments just by rolling the wheel quickly and you get your fine 'shift-key' control
just by rolling it along slowly... all without ever having to touch a shift key.

I don't know about anyone else, but I find the gun controls a little uncomfortable.
Most games these days come with a default configuration using the WASD keys for
movement, I guess that's where this comes from. Personally, I prefer SDFC because
my index finger goes on the F with the little home row nub: pretty hard to press the
wrong keys :) Debated whether or not to throw this in the 'customizable key
configuration' thread and said what the heck.
