I like how easy it is to add tasks or appointments for my clients through this software - especially when they are in different time zones! The notifications could be more frequent so that you don't have to check every few hours/days if something has been updated (it's an app after all).
It would also help me out big-time by allowing reminders of those same scheduled events throughout their work day / week without having them come over emailing asking what was up :) This system allows us as business owners complete control regarding our schedules while working remotely via video chat from anywhere around world at any given moment!!
