It would be great if we could modify the "Add Alert" list of alerts. For Example: for morning appointments, I like a 12 hour alert so I can make sure my alarm is set properly. For some appointments, I like a 6 day alert so I know I have finish something for next week.
Otherwise, I love the product. After using Apple's calendar the first time, I looked for a new calendar app that allowed you to see the appointment subjects on a month view. This has met the need, and I have used it since. Thank you.
