Is your feature request related to a problem? Please describe.
Usually I like to have a general idea of how many cards I have left in a deck, so that I can get a rough estimate of when I would be done seeing new cards in that deck. This is currently not possible to see on Anki’s main screen.
Some of these decks have thousands of cards; others hundreds; others tens.
Describe the solution you’d like
I’d like to see another column with the “Remaining” cards in the deck. This could be colored gray.
Describe alternatives you’ve considered
Alternatives would include opening the notes for that deck, counting the total number of cards, counting the number of cards seen, and then taking the difference. However, this would be a lot easier just to be able to see number of remaining cards directly on this screen for every deck.
