When you duplicate a window, say a worksheet, you will get two windows in Project Explorer with same name. That is ok. But the problem is that you have no way to tell which one is the one you want to edit in Project Explorer. Can we highlight the active window in Project Explorer? It does highlight the active folder.
Currently, the Project Explorer does not highlight the active window. We will consider improving the Project Explorer on this in future.
For now, you can set the Project Explorer to show both long names and short names of the windows so that you can identify the windows easier. Different windows can have the same long name, but short name of a window is unique within the project.
To show both long name and short name in the Project Explorer: you can right-click on the Project Explorer and choose Show long and short names from the short-cut menu.
