There's an option to have mouse buttons enabled or disabled, which is nice. However, for players like me, who singletap with a mouse button and alternate M1/K2, M2/K1, or K1K2, we have no reason to use the other mouse button. This results in accidental taps on the other mouse button, which can cause some really stupid combo breaks (double tapping a circle above a slider causes you to sliderbreak if there's a large enough gap in timing between them). So, being able to disable a single mouse button but not the other would be pretty nice.
