Ideas to improve tree

[geek-merlin]

(You see, i'm starting to love this... ;-)

I see that i can use hierarchy in project and context. I'd really love to see

If these are our tasks:

one
two @foo
three @foo\bar

O want to see this tree (category = tasks)

* (All) = one two three
    * foo = two three
        * foo\bar = three
        * foo\(None) = two
    * (None) = one

And some day i might drag and drop...
