We have done a bunch of small bug fixes and usability tweaks to the Tasks feature we introduced a few weeks ago:

• When a user’s last Task within a card is marked as Done, the user’s name is removed from the list of people shown as being assigned to that card. (Previously you had to do this cleanup manually.)
• When a Task that was previously marked as Done is changed to be “undone” (open/remaining), the user who had previously been assigned to that Task is added back to the list of people shown assigned to the card.
• Bug fix: If someone is assigned to a Task, and this person had previously completed a Done Task, this user wasn’t getting added automatically to the list of people shown on the card. This has been fixed.
