PR Summary

• Enhanced Administrator Control
  Changing the show_admin_column parameter in the register_taxonomy method of the class-venue.php file from false to true allows for increased administrative capabilities. This change enables the display of the taxonomy in the admin column, improving visual management and control for administrators.
