Kontact is the integrated solution for personal information management. It combines the well-known KDE applications for email, scheduling, address book, and notes (KMail, KOrganizer, KAddressBook, and KNotes) into a single interface. Being based on a true component framework Kontact provides exactly the same functionality as the stand-alone applications, and adds more features, by making use of the integrated way Kontact runs the applications as components. Users still retain the choice of which applications are run within Kontact and which are run stand-alone.
In addition to the functionality of the individual applications Kontact provides a summary view and advanced drag & drop features between components.
