Zoho as officially release the new UI (user interface) for CRM. It's crazy cool. It takes less than 10 seconds to figure it out and see the simplicity along with quick ways to work. 

There's actually two new sidebars to understand. It's zippy fast.

The secondary sidebar is dedicated to your tasks. It displays content based on what you choose from the primary sidebar on the left. For instance, you can navigate to different teamspaces, manage teamspaces or add a new teamspace using the teamspace switcher at the top in the secondary sidebar.

Finding the collapse icon is a good idea. It allows you to see more "stuff" on the screen.
