Salesforce App Builder Platform-App-Builder Question # 81 Topic 9 Discussion

The best solution to enable reps to see and access the most-used components from anywhere within the app without leaving the page they are working on is Utility bar. This is a footer that can be added to any Lightning app and can contain tools such as history, notes, or softphone. Favorites, home page, and global actions are not solutions that provide access to components from anywhere within the app. See [this article] for more information on Utility bar.
