If you have ever encountered a situation where a project got delayed, you probably need to change the entire timeline of tasks.
With the shift and extend options on tasks, you can easily extend the duration of your tasks, or shift them in bulk
To perform those actions, first, select the tasks you want to edit and click on "Shift or extend" via the three-dot menu.
In the following window, select what you want to do with the selected task(s).
Extend: Extends the duration of your tasks to the past or the future (moves the start or the due dates) for the selected number of days.
Shift: Keeps the duration of your tasks and shifts them to the future (or past) for the selected number of days.
Then, select the number of days/weeks/months and either the future or past where the tasks will be shifted or extended.
