The ability to add different languages, for example Chinese or Spanish!The system is easy to use but requires more than one training session before it feels like you have mastered all of its features (I used my previous employer's version so I am not familiar).
There are some minor glitches that could be improved such as when adding an appointment time there should appear only minutes after clicking "add". For our daycare center we needed something similar to Microsoft Office Word where parents can write notes about their children without having access through email since internet connection isn't always available in every classroom at school hours.
