It would be really useful to have a constant-current LED driver on the board. A basic spec would be:

2 channels of illumination (more is a nice bonus but 2 is probably fine for now)
adjustable current (ideally not using PWM).
- Basic version: header pin to allow a resistor to be swapped in, and drive with 5v
- Better version: integrate a trim pot
- Best version: add an i2c digipot (if it's surface mount it might not cost much?)
