The new 2.5 release is fantastic.
Two suggestions I have would be:
1. A way to normalize the volume level of all music in the game, and then control how loud or soft it is, so all music would be at the same level, which would be user adjustable. You can change the music volume currently, but the initial volume varies so greatly in each map, it's kind of pointless.
2. A way to disable the scoring indicator on the HUD and still keep the clock/timer.
