Here is what I didn't found in recently purchased Pushback Express – you have all the required activity in the buttons mode but you are missing the voice commands for many of the activities: jetway, fuel, stairs, main door, fuel truck, baggage truck, power truck catering truck. You have the necessary commands to pushback but since you’ve already programmed all the other button steps why not add the voice commands – it would be so much better. On the positive side the pushback function is excellent. This could become a great app.
