What does it mean to block a task?

Blocking a task means visualizing that something disables the team from working on it. The idea behind the card block feature is to freeze a card until the problem with it is resolved.

Blocked tasks are much harder to move - they cannot be moved with the standard drag-and-drop action. To use the feature, be sure to enable the Card Blocking power-up.
