Lightning Experience for Sales Cloud is a whole new user experience that helps salespeople sell smarter, faster, and the way they want. Lightning doesn’t have a tab interface like Aloha does; instead, information is surfaced as needed, so you get it when you need it. Lightning also has a new home page with an Account Insights feature that surfaces any news relevant to your accounts and opportunities, as well as an Assistant feature that prompts your next steps to keep things moving forward. Of course, for users who love the original look and feel, Sales Cloud Classic will still be available.
