1st suggestion: A command that could be used to set the replay speed instead of mashing , and . to get to the replay speed you're looking for. Would also allow for more fine-tuned selection of speed.

2nd: Change the system for setting the damage to similar how the mod flags works: 0 = no damage, 1 = regular damage, 2 = self damage, 4 = object damage. You could add the values together to turn multiple damages on; 1+2=3, so 3 would be both regular damage and self damage but no object damage. 2+4 = 6 would be self damage and object damage, but no regular damage. 7 would have regular damage, self damage, and object damage. Also, with this method, it would be possible to effectively turn off points if you disabled dq, frac, and set damage to 0.
