Thanks for your feedback! As an alternative in the meantime, and albeit not the most ideal approach, you can use the test case selection filter of the Select Cases dialog when creating a test run (from the Test Runs & Results tab) to select a section and its subsections, and once you set the selection this would display the number of test cases selected prior to submitting the dialog. This could be helpful if you need a count for especially large test case repositories with a large section hierarchy. As Marty mentioned, we do have plans to look into this on the Test Cases tab as well, and I've also added your votes to the request. Hope this helps!
