Currently, when you click Run Query in the query execution window, the entire query text in the current window is executed. If the query is large and/or heavily nested, debugging it becomes inconvenient—you have to comment out large chunks of code and then uncomment them. It would be great to add a "Run Selected" mode, where only the selected portion of the query is executed. Many IDEs have this feature. In the snippet below only nested query was executed while parent part is not commented.
