I have noticed two things that were unexpected to me, although I’m not sure if they are bugs:
First, when I go to Options, Editing, Notes, and choose to have a “Different inline footnotes font,” and Apply that setting, it does not change the font of any existing inline footnotes. Perhaps that is intended.
However, I doubt the second part is intended: when I next go to Documents, Convert, Text to Default Formatting, even that does not update the font of existing inline footnotes as I would expect it to.
Let me know if you need more clarification. Thank you!
