Review Data More Easily from the Run Page (Generally Available)
Where: This change applies to Lightning Experience in Group, Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
Why: For a quick view of key metrics in a report, look no further than the Lightning Experience report header. It now displays up to 8 metrics, in the order that they appear in the report, from left to right. These metrics include grand totals, subtotals, record counts, and formula column results.
Also, scrolling through jumbo-sized reports is more manageable. Column headers are now sticky. So, they don’t go out of sight as you page through report records.
