YITH WISHLIST – How to add/delete products via the same button

Hello, I need help concerning the yith wishlist plugin (and I think that many others could benefit of it too):
By default, when you click on the wishlist symbol (p.e. on product archive page), the item is added to the wishlist and when you click it again, you are redirected to the wishlist. I would like to change this function to: Add/Remove the item from the wishlist?
Means:
First click on the wishlist button -> Item is added
Second click on the wishlist button -> Item is removed

Any ideas how to do this would be very appreciated.

Many thanks in advance!
