This SimplePIM ver 1.1.2 is based on SimpleCalendar ver 1.0.2. It has all the features of SimpleCalendar plus schedule reminder/alarm capabilities. Schedule-loaded dates become green in this main window. You can peek at the schedules of a date by mouse-over. If you like our SimpleCalendar for date copying and pasting and wish it to organize/remind your schedules, you might find this tool right for you as a desktop companion. To enter a schedule, simply double-click on the date for it. To edit/organize the schedules, open organizer.
