Hvplot.show() does not return an object

When calling hvplot.show() I expect that either a Server or threading.Thread are returned. Without that there is no way to stop the server.
An example would be:

s = hvplot.show(plot, title=title, **{'threaded': True})
s.stop()

Currently show() only calls the sever (passing on the args correctly) but doesn’t return anything.

              title : str
                  A string title to give the Document (if served as an app)
              port: int (optional, default=0)
                  Allows specifying a specific port
              **kwargs: dict
                  Additional keyword arguments passed to Panel show method.
              """
              if not isinstance(obj, _hv.core.Dimensioned):
                  raise ValueError('%s type object not recognized and cannot be shown.' %
                                   type(obj).__name__)
              _pn.pane.HoloViews(obj).show(title, port, **kwargs)
          
          

          
class hvplot_extension(_hv.extension):
          
          
    compatibility = param.ObjectSelector(
                  allow_None=True, objects=['bokeh', 'matplotlib', 'plotly'], doc="""
                      Plotting library used to process extra keyword arguments.""")
          
          
    logo = param.Boolean(default=False)

This seems like a bug but I could certainly be doing something wrong here.

This seems like an oversight. Please open an issue on Github.

Done. hvplot.show() does not return the expected threading.Thread | Server object · Issue #1115 · holoviz/hvplot · GitHub

thanks!
