Currently, when a user is in the Board view and has collapsed a card, the title still displays and obscured the next card to the right. The only way to collapse the title is to click somewhere else on the sheet. This is visually confusing and annoying to the presenter/user. In the screen shot below, the card for Ken Spaeth is collapsed, but the PM Assigned title is still displayed, obliterating everything to the right. Clicking to the right of the question mark will close it, which is neither intuitive nor elegant.
The idea is to have all data from a single card collapse completely when the collapse (left) arrow on a card is clicked.
