First, CMS Integration plugin documentation is really great made !

I implemented a custom ProtocolChooserExtension to select a remote CMS document.
I also implemented a custom ProtocolURLHandlerExtension to retrieve the remote content of the select CMS document (Example: http://localhost:8080/function/00001/content.dita
The CMS document content is open in a new editor tab.
But I want to set this content in a local file, and open this local file, and I don't know how/when I can do that...
Thanks in advance for your help
