Currently the vacation plug in remove all the product in the seller store and remove all the product pages. Removing pages is not a good practice for google, and we still want to create exposure to the seller and the products.
How can I make this plug-in just block the AddToCart functionaly and show the vacation message on the store and on all the products without removing the products.
We have taken your idea into our consideration. To get this kind of feature you have to customize the plugin. I will discuss this idea with our developer team. Hope they will implement this idea in near future.
And I hope that if I there's anything else I can do for you, you won't hesitate to let me know.
