Add parameters to method definitions

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create test.py
class Test(object):
        def __init__(self):
                pass

        def big_universe(self, why_not, agree=False):
                if agree:
                        print "Agreed!"

def testing(hello_str):
        print 'This works', hello_str*3

if __name__ == '__main__':
        Test().big_universe('hello world', agree=True)
        testing('!')

2. Run pynsource -> File -> Import python code -> test.py


What is the expected output? What do you see instead?
Expected 1: "big_universe(self, why_not, agree=False)" in class Test with 
method parameters and default values
Shown 1: "big_universe" in class Test without method parameters
Expected 2: A plain white color
Shown 2: A mild blueish background color

What version of the product are you using? On what operating system?
1.61-src.zip / Ubuntu
1.61-macosx / Lion

Please provide any additional information below.
PyNSource is great! It would be relatively easy to go over a small project 
using class diagrams that contain method parameters and its defaults if any. 
Ability to toggle this and the background color would be great.

Adding parameters to method definitions - I will consider this.
