Need a little more functionality from your Salesforce Lightning experience? We have a nifty feature where you can add an Utility Bar to any of your apps. This utility bar contains an assortment of helpful components that can be accessed directly from the bar, all without leaving your current page. A great feature to add to any of your apps!
So what exactly are the features of the utility bar? In a nutshell, the utility bar contains components from the home-page and footer of Salesforce Classic, such as chatter feed, recent items, notes and more. By sticking them on the utility bar, which, once activated, will always show up in your designated app, you will save yourself the trouble of going back to the home page!
