I hope to see a demo of basic Project Management and Task integration:

3 components - Projects, Tasks and Resources.  

1) A Resource (Person) should be able to look at all their assigned tasks across all the projects, 

2) a Project lead should be able to look at all the tasks their resources have to judge who has availability for new tasks

3) Conversely - one should be able to look at all the tasks across all the projects to see what tasks may be falling behind, rather than going plan by plan - one at a time.

Additionally:

as Stefanie and others have said - Integrate Onenote to have tasks assigned directly  or integrated:

As an example,  :

In Onenote - I assign a task to a person.

It goes to their Outlook,  They can look at it but it's not related to anything - other than a link back to the onenote. - Nor can it be related to a Plan/Project In Outlook , nor can the assigner  do anything with it or see it (Other than scanning the Onenote.

The assignee can open up "My Day" in Teams (if it was set for today) -  Move the task to a Plan - where it's no longer assigned to them.

Then someone has to assign that task back to the original with perhaps a proper date 

Either way - It's a multiple step process 

And don't get me started trying to do that with Loop ,  Loop components owned by individuals / Not Teams -
