After introducing this feature in the mobile version, we’ve decided to add it to the regular version as well.
From now on, users will be able to mark tasks from any task list by clicking the corresponding star icon. Tasks marked across all your projects are displayed under “My Office -> My Tasks -> My Marked Tasks”. Each user can mark their own tasks. The other users’ marked tasks are not visible whatsoever.
Marking tasks is great for identifying tasks that require more attention than others (e.g. urgent, critical or overdue ones).
At present, this option is not available in Gantt charts however.
