* crouch toggle
* always sprint toggle
* independent x and y sensitivity adjustment
* field of view adjustment
* in-game gamma/brightness adjustment
* in-game save slots (possible quick save/load feature, too?)
This is tricky. The gameplay was designed around the current system. I plan on looking at supporting alternate save systems in the future but not until the core game support is complete.
* separate music and sound volume sliders
* mousewheel changes selected weapon
* option to disable the F key cheat
These are already planned.
