Zimlets are applications that enhance the user experience from the Zimbra Web Client. Some Zimlets are automatically deployed when ZCS is installed and you can add new Zimlets and manage existing Zimlets from the Zimlets Configuration page on the administration console.
To see a list of Zimlets that are deployed, click Zimlets in the Configuration Overview pane. The Content pane lists all the Zimlets and their status -enabled or disabled. You can upload and deploy new Zimlets. Zimlets are delivered as a zip file that includes all the files necessary to run the Zimlet.
See the Managing Zimlets chapter for information about Zimlets.
