We use parents in our requirements so from Requirements I always view as a Tree. When I am in a test case and click the Traceability tab to link to a requirement and I use "Show Requirements" it only shows me a flat list in ID order so I have to maintain an XLS cheat sheet to add so I can see in tree view. It would be a GREAT enhancement to PractiTest to be able to choose Tree View from the Test Case Traceability tab on Show Requirements and save me a ton of time. Thanks :)
