adding field to Webuser list in Manager

Hi,

Where should I go(What files should I hack) to add in to the webuser manager’s page a fields previously added to the modx web_user_attributes table ?

We added a ’company’ field to the websignup process and deal with it in a specific dev, but I’d like to SHOW this new field in the manager, in order for the people who manage the user’s list to see everything here too with other user’sz data.

Thank you.
