Speedbooster without HiJump will reduce Samus' jump height when running and turning Speedbooster off will enable her to jump normally while running.
Disabling HiJump will give more time to perform a mid-air morph.
Disabling Gravity will allow Samus to float farther in water, or jump slower for a mid-air morph.
Beams may need to be disabled to control how enemies are killed (i.e. Remove plasma for canUseFrozenEnemies, or remove ice to effeciently use heat room farm points).
