Chaos Manager

Chaos Manager is a compact organizer that includes an appointment/to-do manager, a calendar, contacts, a notebook, print/import/export and more.

It can remind you of appointments via popup dialog, or optionally send email reminders to a specified email address - allowing you to get reminders, even if you are away from home. If you commute between 2 computer locations, you can use the built-in FTP synchronization feature to exchange and sync data with another install of Chaos Manager (e.g in your office). Additional features include password protection, customizable interface with many skins to choose from and more. As far as features, Chaos Manager is a mostly basic PIM, but the FTP sync features and email forwarding add some good features that may be more useful to some, than other advanced organizer features.
