F12, always hated the restrictions on the size of the weapons, due to overlapping.
Also, another small thing that sort of goes hand in hand with this:
I'd like a separate set of images (yes, I know my suggestions always involve adding more separate images) for the death console. I made a really nice looking weapon menu with larger images, some on the left and some on the right, with custom text carefully positioned left/right of each image, and I completely forgot about how screwed up the death console would look in-game.
