list_folder/continue for file id

Hi Jackson, this endpoint isn't time based exactly; when you supply a path it acts as a sort of filter on the events you'll get back. Suffice to say though, the behavior you described is expected, and the best way to handle that case would be file ID support for /files/list_folder, so I'm sending this along as a request for that. (If you need to stay up to date with the full state though, you should use the root "" path.)
