Things *I* have a problem with
That heat bar is so tiny, only the warning that i'm overheating tells me that i am in fact, overheating. I want it big, sideways, and in the lower center part of the screen.
Color coded weapon groups/TYPES. Out of the corner of my eye i want to be able to tell that my missiles are still reloading but my Gauss Rifle is once again ready to rock. I want to be able to see that without looking at it. Also, increase the Size of the weapon text, OR even better yet allow me to toggle weather or not i want to see the list of the name or just an Icon of the weapon itself. An icon of a long blue/red/yellow tube is different beam weapons, while a long rack with holes in it is an LRM. Regardless of what weapon group i may have it in.
Radar, I want to move it. Me personally i want it in the upper left hand corner where all the other games put their mini-maps, and in the upper right i'll put the radar screen. I'd like a sweet toggle that will expand it in the middle of the screen but still very opaque that will switch between the two or even combine the two of them at the same time at the touch of a button.
Let me dim the background cockpit screens lights. I can do that in my car, after all.
Give us Unique mech dolls to represent our targets. I'm a huge fan and i of course love the generic mech doll too but when i'm targeting something over a hill I want to be able to see what i'm firing at without looking at it. I have a real grudge taking my eyes off the battlefield to look at something my hud should be offering on a silver platter while saying "yes sir, may i have another."
Modes: I dislike having them hug the radar screen. I'd put it under the weapon's screen, not next to the radar screen. Yes this is more then likely a personal preference.
And alot of this cosmetic hud stuff? Don't make us change this in battle, give it to us in an option's menu.
