Query lists can get quite large with dozens or hundreds of items inside. Allow the user to sort the query list by result. E.g. if a query returns "Has Results" show them on top. This makes it easier to focus on the relevant results.
In addition the title bar of a query list shall display the amount of queries. Once the user has executed them (green play button), also display the amount of queries with "Has Results".
Before executing them: "30 | --"
After executing them "30 | 4"
This would indicate 4 out of 30 queries have results".
