Before my wiki transitioned to UCP, I made frequent use of the "Most Popular Pages" feature under Special:Insights in order to prioritize pages for improvement.
Currently, I can only see the number of page views for the top 10 pages under Wiki Analytics. However, I've found that the low-hanging fruit tends to be in the top 50 or 100 pages, not the top 10.
Please consider expanding this or adding new features to help with this in the future. (Thanks!)
