App Name: Launch It! by OyeCode
Type: Chrome Extension
Purpose: Click the extension icon to toggle between Salesforce Classic and Salesforce Lightning views
Get it: Click Here!
Comments: Most hacks previously used to get to Salesforce1 now redirect you to Salesforce Lightning (ex: adding one/one.app at the end of a URL). This app appears to have been built to toggle between Salesforce Classic and Salesforce1 but now quickly redirects you between UI’s.
