The bigger pane which is displayed when a test case folder is clicked is ambiguous. For example see below where GBL-P2P has a sub section called "Supplier Management" which has few test cases. But when you view GBL-P2P it gives an impression that there are not further subsection or test cases under it
Supplier management folder:
It would be helpful to have visibility to all test cases within a folder and it's sub-folders. Even if the test case count was displayed, then we would at least know the folder isn't empty. This could be similar functionality to what is used when selecting test cases to be added to a test run.
