This calender has the best interface of all. It is designed to keep track of appointments at a glance throughout the month. Because it is an appointment based calender, it desperately needs two improvements: first a link to contacts from task setup so the contact info/address(for GPS) can be accessed from the calender. Second, a simple red circle notification icon to let one know there is an upcoming appointment; not everybody wants to use the data or e-mail services for alerting. If these 2 improvements are added, this application will become perfect & I will buy the full version in a heartbeat, as will a lot of others. I hope the developer considers this.
