Gmail offers several features beyond just email including labels to organize messages, contacts groups, calendars to schedule events, and documents for creating and sharing files. Users can create labels instead of folders, add multiple labels to messages, and organize contacts into groups. Calendars allow creating personal and other calendars that can be color coded and shared. The documents feature provides an interface similar to Microsoft Office for creating documents, spreadsheets and presentations that are saved to the cloud and can be shared collaboratively.
