Unable to retroactively make a post reply into a whisper

I’d be interested in mockups for an even clearer whisper-on editor though. I think the editor should look quite different when you’re writing a whisper.

We did make some improvements here since that was written. The “Reply” button now changes to “Whisper” with the eye-slash glyph, plus the slash-eye glyph is also in black near the reply area at the top.
