Couple of small quality of life improvements:
Allow private multiplayer lobby hosts to select which penalty types they want enabled. In our league we find that 99% of all "SEVERE collision under safety car" penalties are too harsh or apportion blame to the wrong party and need to be removed after the race.
Make the ERS increase/decrease buttons switch between modes 0 (off) and 2 (hotlap) in qualifying. Currently these buttons only work during practice.
