I like how easy it is for me as an average user with no programming experience whatsoever! Once you've used this software once or twice (which was surprisingly enough very fast), getting started isn't too difficult at all since most things are self explaining - there's even help guides available in different languages :) The interface can be improved sometimes but other than minor glitches nothing really bugs my attention here ;) Really quick way of keeping track what has been done so far; great stats tool which shows where your plane spends its time / when maintenance checks would have gone better etc.; being able calculate times spent away from home/home base area without actually using up hours manually ; saves much precious flight crewtime compared eith manual data entry!
