Within Selenium IDE for Firefox, under Options -> C# / NUnit / Webdriver, there is a button 'Source' to view the conversion formatter.

It is displayed in read-only format.

Is it possible to get access to this file in order to customise the export process?

Sorry if this seems like a trivial question, I've found plenty of people complaining about not being able to perform various tasks online and a few responses that indicate that custom export is supported, but I can't seem to find a way to access the file to perform the work.

Thanks
