I don’t know if this is intentional or not, but when I’m typing with the inspector displayed, if I’ve not input any text into the ‘synopsis’ box, it autofills with the contents of the document (the text doesn’t show up immediately, but switching to a different document and then switching back should make it show; as far as I can tell it updates to include any new typed text).
This text disappears upon clicking into the box, and the behaviour stops if any text or punctuation is manually entered, but as long as it’s empty it seems to do this. I’m not sure if this is an intended feature or a bug, but as it differs so greatly from my experience in Scrivener 1, and as I haven’t seen anything mentioning it as a feature and I can’t find an option to deactivate it, I figured I’d check.
