This article will show you the feature of recycle bin directly on the Agile board. It means that if you wish to move to your Agile card to the "closed" status, there is no need to have the "closed" column itself. In this way you will spare space on your Agile board.
Just as a comparison, you can see how the board looks like with the column added.
So, when you make sure that there is no "closed* column, please just try to drag an Agile card and then instantly the recycle bin red rectangle (i.e. a shortcut to the "closed" column) will pop-up at the bottom right corner.
Just drop the card in the bin and that's it. It is now moved with this simple movement.
Please note that the "closed" column actually means the issue statuses that have Issue closed parameter enabled. It can be done or checked in Administration - Issue statuses.
And the Issue closed parameter is checked/unchecked in the specific issue status settings.
Note: So, this means that if you wish, you can have more than 1 recycle bins.
If you wish to see the feature in more detailed way, please check the video demonstration below.
