A custom display would take care of that.

Hmmmm, unless you can get to the attachment via a URI, I think this is
outside the scope of the file chooser.

Oh, one thing that I didn't mention in the spec is how extensions can
know if the file chooser is showing only files or also URIs.  I don't
think you can get that information right now.

The spec draft mentions exposing GtkFilePath to extensions, which makes
me very uncomfortable.  GtkFilePaths only make sense in the context of a
particular implementation of GtkFileSystem.  This in turn has methods to
convert to/from URIs and filenames, so perhaps extensions should just
see URIs instead of abstract GtkFilePaths.

Only if the file chooser is configured to show URIs.
