I make heavy use of the modules to arrange my test cases in alogical manner as this also aids me in reporting on specific aspects of our system
When viewing the Tests cases tab though, none of the tests that I have show up as they are all in the modules, I can only view the test cases for the module I have selected.
What would be great is that when I click on my top most module, all tests cases of all the child modules should show in the list, as this gives me a great overview of the current standing of events in my system.
