Display Projects' Global View as a tree list

Hi.
I'm looking for a way to get the whole overview of my items as a tree list. I know that both "Follow up > Timesheet" and "Follow up > Planning" do this, but they don't include Tickets.
On the other side, on "Work > Global View" I get the whole list of tickets, activities, milestones and actions on a single view but not as a tree list.

I believe that a similar tree list would be important, since we could get an overview of all activities and related bugs/incidents not only from a Planning point of view, but also as a general view. Then we could go over and include also everything on this tree list: a general view showing activities, incidents, meetings, case studies ....

Perhaps your Projeqtor already includes a similar view? In this case may you please show me this?
Otherwise, I would suggest this evolution since it would be really helpfull to get a general overview of relations between every action/meeting/case/risk related to its parent item.

Best regards

Many thanks for your reply.
However I faced probably into an issue on this, I've posted it on Issue section.
