WDQ is the tool where you define and run queries on the Wikidata data. It is not on official tool, it runs on replicated data in Labs and, it works really well.
While you prepare your query, you will see the number of results and the first 500 results. They are the maximum number of results that Wikidata provides when you request for information through its API.
When the query definition is satisfactory, you could create a "permalink" for future reference. What is new is that you can move on to the "AutoList:". This is where you can page through all the results and select items for special attention.
