Customization of/ and advanced bookmark features

We’ve heard from many users that they’d like us to evolve our Bookmark feature to include the following:

1. It would be great to move all bookmarked to a new deck with one command. As is I need to copy and paste each card separately to new deck

2. It would be nice to remove the bookmarks for an entire class.

3. The bookmarks of delete classes or decks are still on the bookmark tab in the app and cannot be viewed nor deleted. I would like to be able to delete them and ideally they should disappear when you delete the class or deck

4. Bookmark flashcards in Certified Classes that I want to study (I don’t want to study the whole thing)

5. Start a study session from the carefully curated set of bookmarked cards
