All the missed deadlines are collected in one column for your convenience. You can hide this column from your view and pretend it never happened.
To hide / show the Overdue section, mouse over the “eye” icon and click on the “Overdue” link.
The number of overdue tasks compiles the undone deeds of everyone in the project (absolving you of sole responsibility). That’s what you can keep telling yourself.
If there’s even one overdue task in active projects (and remember, it doesn’t have to be your task), the “eye” icon goes red. After exceeding 10 - your computer’s self-detonation sequence is initiated.
