When "Totals" is selected, on mouse over still display average values for the metrics
When we change from "Avg. per execution" to "Totals" the row order can change.
With bigger numbers, it becomes harder to quickly know if the average is high or not to decide to take a further look.
Instead of need to "Track query" and then click back and forth with "Avg. per execution" / "Totals" having the average on the tooltip when "Totals" is selected will be helpful.
