When a user starts logging on chrome://net-export for desktop they are prompted with a file selector dialog window. Right now the default path that the selector opens up with is the user's home directory. It would be more user-friendly for the default path to be the last directory the user tried saving the NetLog dump to. 


In net_log_file_writer.h the dictionary value returned by GetState it would be good to change this to return a
std::unique_ptr<base::DictionaryValue> instead. Or if you can file a bug for
this.
