I’d love for a future version of Scrivener to take snapshots of all three text containers in Scrivener (Main editor text, synopsis, and document notes). When restoring, it would be very nice to have a pop-up that allows one to pick which of those elements to restore, much like “convert to default text style” lets the user pick which formatting elements to preserve/convert.
I imagine the hardest thing to do (as if this isn’t hard enough) would be providing a sane way to compare synopses and document notes, since there isn’t a second inspector, so I can understand that you might be reluctant to do that. However, I’ve seen suggestions about manually copying a synopsis and/or doc notes into inline annotations before a snapshot–if that idea could somehow be integrated into the feature, or at least into the comparison display, it would at least provide the information, even if the display isn’t as pretty as two inspector panes.
