Changing the "applications" SoapUI and ServiceV using the tabs is completely inconvenient, as you often switch from one to the other for testing your own mock whether the latter works as expected.
If you switch back to the ServiceV tab, the view is in an initial view, so that you have to search&click through to your script/edit textboxes.
It solves the main problem and creates a nice experience if one could open all those "application tabs" in several separate windows (on your second/third/... monitors).
