I've always thought that the "white boards and post notes" approach to agile work management is the ideal, it's just difficult to achieve on the 'mortal plane' with remote workers, bad handwriting, inability to query / archive etc. With that in mind I really like Trello because it feels very close to a digital version of that ideal. https://cardboardit.com/ https://cardboardit.com/ is another product in that vein (I am unaffiliated with both products).
