In case if you have several instances of Service Studio opened, for example if you need to connect to two environments, and when you need to switch between them or return from another application - it's not easy to understand where to go to, because the window title is  saying simply "Service Studio":

Meanwhile other applications usually have title starting with the document name, which makes it much easier to choose the proper one:

So the idea is to follow the same pattern in Service Studio and start the title with active module name (and possibly environment after it?). If there is no opened module - then environment only.
