Osmo is a handy personal organizer, which includes calendar, tasks manager, address book and notes modules. It was designed to be a small, easy to use and good looking PIM tool to help to manage personal information. In its current state the organizer is quite convenient to use - for example, the user can perform nearly all operations using the keyboard. Also, a lot of parameters are configurable to meet the user's preferences. On the technical side, Osmo is GTK+ based tool which uses a plain XML database to store all personal data.
