How to automatically count amount of cards in Trello?

If you use the List Limits extension (Power-Up), it will count them for you. You have to add a maximum limit of cards the list can have, and it will show as ACTUAL_NUMBER / MAX

All you have to do is keep the filter "*" on.

I am using this extension for Chrome: CardCounter For Trello.

This extension shows me the total cards that I have in my board.

Click on show menu on the right side of the board if its not visible.

From the Menu option select Search Cards.

In the text box type * to "filter by everything".

All cards will remain visible and you'll also get card counts at the top of each list.

This only works in the web version of Trello.

If you use Chrome, there is an extension called CardCounter

It does the job but i'm looking for something nicer.
