Super class methods presentation

Hello,
I'd like to propose enhancement to presentation and overriding methods of super classes.

Let's take this simple code:

class First(object):
    def method_one(self):
        pass


class Second(First):
    pass


I'd love to see some kind of icon on the left of editor (like + and - to fold/unfold class code) that would show me all super classes methods, let's say grayed, as a code  at the beginning of Second class.

class First(object):
    def method_one(self):
        pass


class Second(First):
    def method_one(self):
        pass

    pass

Now, providing any entry on method_one would do the same as Generate.../Override Methods feature. To make it less space consuming, super class methods should show up folded, with possibility to unfold to see whole code.
Methods should also be grouped by super classes from which they come:

class First(object):
    def method_one(self):
        pass


class Second(First):
    object
    def __init__(self):
        ...
    def and_so_on(self):
        ...

    First
    def method_one(self):
        ...

    pass

In my opinion it could provide nice form of methods presentation, and quick and easy way to override them. Could be particularly useful on CBV in Django, where multiple, user created super classes are being used.
