Two suggestions, the PCF8574 etc. has the ability to generate an interrupt on the host on change of input pins. It would be nice to have that feature available with this expander.
Also, power save/sleep mode. Some (most? all?) of the targets this can be used on have sleep mode and wake on change. I'm not sure if that would be enough to wake on I2C activity or not but it would be another nice thing to have if it can be implemented.
