report view: window to show table like note summary -> get an overview of your notes now!

I am still searching for a way to get an overview of all the notes and this is my suggestion:
(note: in my example I will use 'tasks' but the concept can be applied to any kind of note)

Let's assume you have hierarchical tags representing tasks - the status of a task - the person the task is assigned to and a project context.

TASK
TASK/open
TASK/in.progress
TASK/waiting
TASK/closed

assigned.to
assigned.to/Peter
assigned.to/me
assigned.to/Susan

project
project/p1
project/p2
project/p3

Now you want do get an overview of all those tasks:
 - which status do they have?
 - which person is in charge?
 - which project does it belong to?
 
What I want to suggest is that we can open a report view (special window) to show something like the screenshot below shows!
We could define the tags that should be used for the columns (their subtags are the content of the column)
and we could define which tag/column should be the one used for sorting.



How do you like the idea.
At least to me - this would be extremely convenient.
