When I click a context in the list on the left and it shows the actual source code or form in the "Sources and Forms" window, there's no indication of what file it is. No name, no path.

This is fine if your project only has a few files, or you know the project intimately, but once you have a few dozen contexts in an unfamiliar project it's less easy to figure out where to make any fixes you might need (e.g. some text that needs to change in the source file because it is incorrect).
