I started trying to use Smartsheet to manage my daily workflow using the Card view. The problem I ran into was when I created a card with subtasks and then completed the card, moved to the card to the "complete" column, the subtasks on the card stayed in the original "in process" column. I found this very inconvenient and really untenable to utilize Smartsheet with subtasks for my intended purpose. Please consider how subtasks could be moved automatically with the main card.
