I tried to guess at what was meant by "Moving directories around", and I could easily have gotten it wrong, so please re-open the issue with more information if I haven't addressed the issue.

What I tried was the following:

1. start editor
2. open a directory
3. close editor
4. rename the directory opened in step 2
5. start editor

Editor doesn't like this, printing a message and stack trace to the log (included below), but this behavior is inherited from Eclipse and I don't think we can do anything to change it. (The directory is shown in the Files view, but is marked as being "closed", a concept that we don't expose in Editor and from which the user cannot recover.)

The log entry is:
