Replacing Related Lists with the Related List Quick Links Component
Scrolling through several related lists to find the right one is time-consuming. With the Related List Quick Links component, users can hover over links to see all the related list columns without opening the View All page. Users see all options at a glance and can find the right one faster. Users can also customize the quick link order in their personal settings.
RECOMMENDATION: Replace all Related Lists components with the Related List Quick Links component. If there’s a related list that should be easily accessible to users, you can add a Related List – Single component. If a page layout includes many related lists, consider moving some to a second tab.
RESOURCES:
News and Twitter
Having the News or Twitter component directly on a page can cause the page to load slowly. Your News and Twitter components should be placed behind a tab. This will make sure that they are loaded only when you click on a tab.
