Allow More Than One Message Exchange Window to be Opened at a Time

When executing a test case within the SoapUI NG GUI, you should return message response viewing to the way it was before NG - you should be able to view the responses for more than one step/iteration at a time and the window should be opened as a separate tab to the right of the test case tab. Opening a message exchange window in a separate window and only allowing one to open at a time does not allow me to view results of iterations side-by-side. This was a valuable function for debugging data-driven tests that had failures on selected iterations. Please return the message exchange windows to their former functionality.
