taskcoach mods

I am finally getting around to implementing a feature I have wanted for 
a while.

This message has two parts. 

1) is the question, how do I go about getting SVN write access, and what 
is the development process.
2) Here is what I am trying to do, and my approach for review

Feature:
When you double click on an item (task) in the treeview, I would like 
the viewer to automatically open to the field that you clicked on.
For instance,  If I click on the categories column, I want the viewer to 
open to the category tab.  If I click on the "Start Date" column, I 
would like the "Dates" tab to show and the "Start Date" column to have 
focus.

Approach:
It is not hard to get the column that is clicked on from a treectrl,
the column number can be transfered to a "field" that the viewer will 
know about. (I have not figured out the mapping, but I suggest it be 
stored in the treectrl somehow)

I specifically want to add a kwarg to that viewers should process called 
"openOnField".  If the viewer doesn't process it, there is no harm.
Then the task viewer can use "openOnField" to set the correct tab and 
set focus to the correct field.  I can add support for other viewers if 
there is a desire.

To do this, I need to be able to pass all this information through the
