I would love to see a true datasheet, and particularly a block system diagram showing signal path and tolerances. Knowing designed and/or tested noise, slew, and ESD parameters would allow for proper care with signal conditioning.
Moreover, things like input impedances, sample timing error, and other device documentation would be much more intuitive in a graphical diagrammatic (perhaps even interactive) format.
Also, please include operation characteristics and designed behaviors for the whole device in the user guide. Right now, for example, the behavior of the LED is unspecified. The device is plug and play (with the beta driver), but for first-time users, this is not mentioned in any documentation included in the packaging or online, even if it's intuitive.
