The calendar setup is a mess. We need to be able to add events and see them, sorted by day. A list of every even is confusing and not helpful as far as organization. You should take a look at every other calendar application out there and see what a useful, organized calendar app looks like. As for mail, it's not the worst but it's also not great. It's the calendar that professional organizations need and if we cant get use out of it your doing a disservice to the many many companies who want to use your program.
