Improve Your Lightning Pages with Guidance for App Builder
Where: This change applies to Lightning Experience in Group, Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
How: Tips are available for categories such as performance, usability, and structural issues. Some issues that the tips cover are also captured in the Salesforce Optimizer report. For example, if two components on a page are identical, you see a tip that tells you so. After you fix the issue, the tip disappears.
If there are tips available for your page, you see an indicator icon on the Help menu.
To hide the tips docked prompt while you design your page, go to the Help menu and select Mute Tips. You can reopen the tips prompt by selecting View Tips.
