Smart actions
If text has an address, a phone number, or a date, Library offers actions for it. Press Tab in Quick Open to see them: Open in Maps, Copy Phone Number, or Add to Calendar. Detection happens on your Mac.
Smart Punctuation
In Copy as, Smart Punctuation turns straight quotes and dashes into curly quotes, apostrophes, em dashes, and ellipses.
Smart titles
Turn on Name new bookmarks from their pages in Settings > General. It is off by default. A new bookmark then takes the title of its page.
Library reads only the start of the page, and it requests each new bookmark's page once.
Smart sorting
In the Edit Library window, open the sort menu in the header. Choose Most Used or Recently Opened.
