In some of our workflows, we use a card to encapsulate a project. The description becomes a living spec document that can grow quite large. We leverage multiple checklist groups to categorize our work items (in a similar vein to lists on a board). Having a way to collapse/expand the description in a card will allow the checklists to be more immediately visible upon opening a card. Currently, the checklists are always off-screen and we need to scroll down to see them.
