Extra Stats in Deck Browser

Anki Add-ons
1

I’ve created an addon to display extra stats in the deck browser.

At the moment it’s extremely simple. Just adds two columns to display “unseen” and “total” for each deck.

More functionality may be added.

I’m getting the following error upon starting Anki:

Error
An error occurred. Please start Anki while holding down the shift key, which will temporarily disable the add-ons you have installed.
If the issue only occurs when add-ons are enabled, please use the Tools > Add-ons menu item to disable some add-ons and restart Anki, repeating until you discover the add-on that is causing the problem.

I’m not the author but I have patched it:
go to tools → addons → select the extra stats in deck browser addon → view files →
then just change these lines in “init.py” so that it casts these strs to ints

                    #This gets the total number of cards in the deck.
                    num_cards = mw.col.decks.card_count(int(id_num), True)
                    #To get other stats data, we need to select the deck.
                    mw.col.decks.select(int(id_num))
