We have used https://wordpress.org/plugins/ti-woocommerce-wishlist/ for wishlist.

We have used custom wishlist counter icon for dello. For example please check screenshot.

 By default after adding wishlist a succesful notice popup will arrive. If you do not want to show pop up then you can deactivate by going Admin panel–>TI Wishlist. Please check screenshot.

You can access all settings of wishlist byfollowing this documentation.
