Personal Information Managers for Linux
Having used a hierarchical personal information manager (PIM) under Windows for a couple of years, it was a shock to come to Linux and find that nothing of the sort seemed to be available. There are some hierarchical systems, to be sure, but none of them are particularly simple and easy to use. Without a hierarchy, things get complex very quickly, and a complex set of tasks in a complex program is a recipe for disaster. I tried a few other applications including Evolution, found them overly complicated, and settled on OSMO. OSMO may not be hierarchical, but it has the advantage of being simple.
OSMO can be installed in Ubuntu via the Add/Remove option on the Applications menu. It's also available by download from http://clay.ll.pl/osmo/, where you may find a newer version. OSMO opens by default as a dialog box with six tabs: Calendar, Tasks, Contacts, Notes, Options and About. Any or all of the Calendar, Tasks, Contacts and Notes panels can be hidden if you don't use them.
The Calendar panel shows a three-month view with the current month larger than the two others. Buttons at the top allow the user to navigate in steps of a day, a month or a year. There is also a 'Go To' button to jump directly to any date. Clicking on a day on the calendar allows the user to enter appointments or tasks for that day in a panel at the bottom of the window. A full-year display and a date calculator are also available. Appointments can be indicated ahead of time with an alarm which runs a command, and recurrent appointments and events are available. Existing date and appointment information can be imported via standard iCalendar files.
The OSMO task list is a simple alphabetical list of tasks with a notes panel at the bottom for details of what's been done and what's required for each task. Double-clicking on a task name opens a task editing window. Tasks can be assigned to categories, and completed tasks can either be hidden, deleted, or shown with text crossed out. Tasks can be given a due date and one of three priorities -- high, medium or low. An alarm can be set to warn about due dates, and the task list can be printed.
