Just wondering if it might be nice to have the DTC explanations for codes included in the firmware, so that when scanning you can press a key for more info etc and get a short explanation of what the dtc code is, that would save having to have a PC near to read the Dtc section in the tune tool etc.
(ie) means the scan tool has all the info you need to figure out whats wrong there and then.

(eg) P0102 ... click F1 or something for more info and get "MAF Sensor Circuit Low"

Shouldnt take up much flash space and makes things more polished
