All information can be viewed and sorted in a variety of ways. A Professional version of BrainForest will be available soon, which will include a desktop application, specialized tools and templates, and expanded import and export capabilities. It works in conjunction with the Pilot's Datebook software to display one or two full week's worth of appointments. It allows for fast and easy editing of appointments, and instant viewing of any attached notes. WeekView is especially useful for scanning future time periods to check for conflicts in your schedule.
Many applications are available on the Internet, either for free or as shareware.
