Okay, I see that I'm the one who has been misunderstanding.
You are correct that there is code for bookmarktags and bookmarksummary--that's what I thought we were talking about. I didn't realize "Private Bookmark & Rec flags" were separate settings on a bookmark.
After a little research, it looks like I could probably collect the current settings of those flags.
But what you want them for? Completionist impulses? They're
your settings...
And yes, the
GitHub repository is the code base I use and update.
