This simple Anki addon inserts a Review button that's adjacent to the 'Study Now' button in each deck's overview page to quickly schedule a custom study session with decks marked as 'Learning' and 'To review'." It can be triggered with the Shift+R shortcut. This makes it much more seamless than the traditional method of launching a Custom Study, choosing the Study by card state or tag, selecting Due cards only and then clicking on Choose Tags.
