Renaming files from a window title bar broke some years ago and has never been fixed. I most often want to do this in Preview, but every other app with clickable filenames in the title bar has the same problem.

The filename in the title bar has a down-pointing chevron next to it, indicating you can click it. You click it. A small drop-down window appears with the filename, the tags, and the folder where it is located. You edit the filename and press Return, as you would when renaming the file in Finder, or as you would when completing any text field. Nothing happens. The file isn't renamed.

Only if you press Tab (?!) is the file renamed. Insanity.
