When preparing to execute a test case there is no easy way to see previously logged defects.
Currently in a test run if you select a test case in full screen (where you can View/Edit Case, Add Result, Add Comment, etc.), if you want to quickly review previous defects logged you have to VIEW CASE, then select the Defects tab. You have now left Test Case Execution and must use the browser back button to return to the test case. This can be confusing.
Recommend adding a VIEW DEFECTS under Add Result and Add Comment, that brings up a pop-up for review of the previously logged defects.
