Now, we’ve had the ability to search for Kanban cards on the board for some time now, via the Filters feature on the options tab. But this is something completely new. Now we have made kanban software that allows you to really search for cards, using an advanced search dialog box.
Also look for the search link in the top right corner of the backlog and archive. Be sure to try the “go to” link for cards that are on the board, to see the board scroll to the location of the card and make it flash to identify the card you’re looking for.
