e.g. I receive an email for something I need to do and then of course it gets lost in all the emails despite tagging. The kanban board would have certain heading e.g. to do, done, waiting or what ever suited me and I would move the whole email and attachment (if any) to it so at a quick glance I could see all the emails I need to do something with in a specific box on the board. The board could have as many boxes as needed and would really be another way to view the emails quickly
