Add option to Expand and Collapse all groups

Hi,

You can collapse or expand all tasks by level using the following keyboard shortcuts:

To collapse all tasks by level: Shift + ←

To expand all tasks by level: Shift + →

Using the keyboard shortcut I mentioned, it first collapses the tasks and then groups. Just to confirm, would you like to collapse groups only, without collapsing task levels?

Hi, I am not looking into collapsing/expanding tasks, but groups.

You are right, it collapses groups too, so would work for use case - showing team members amount of tasks everyone has. Would never find it myself since I am not using shortcuts really, but it's not something often to do so is enough
