I am sorry is the solution is obvious, but how do you wishlist games, now? It used to be easy, but now I can't find the option at all? Was it removed?

Your adblock filters are set too aggressively. The wishlist button is in a social div, and your adblock is not allowing it.
Wishlist button should appear next to facebook, twitter and g+ buttons.

Or if you like your adblockers as much as I do, just add item to cart, go to cart and move to wishlist. :)

Yeah, it seems to work if you add it to cart, like sunshinecorp said. Or you could disable the filters and keep Adblock Plus:

I would recommend the cart method.

I hope GOG realizes that the Wishlist button is not a "social div" that should stand alongside Facebook, Twitter and the like; and they separate it out.

Someone pointed that there were talks about options to make wishlist public and there was especulation that it was the reason to put that button next to the others. Who knows?

I don't know why I didn't remember you could do this. Thank you.

I don't understand why wishlisting is a social feature. What next? Link to facebook or say bye bye to your library?

I don't understand why they merged the wishlist button with "social media" either. I wish they would change it back.

There is a div class called socials--flexible that contains a div class called socials__list. Inside said div are 4 items, social-btn--fb, social-btn-tw, social-btn--gp and social-btn--wl, all 4 under the ng-scope. Does your adblock remove the buttons or the whole socials--flexible div?
And how does AdBlock choose to remove those? Is it due to them being named social? Is that because the div contains facebook/twitter/G+ code?

And you should be able to whitelist the social-btn--wl, unless AdBlock decides to remove the whole div, which would be really stupid though.

Basically AdBlock (and other javascript blocking programs) decide to "delete" the whole bar of buttons, both social media and the wishlist. I tried to individually block the social media buttons such as "social-btn--fb," but it didn't work. I think the only way this can be fixed is if the wishlist button is in a separate div entirely.

So it's not deleting the buttons, but the whole div? So even if the button was called "btn-wl", it would still be deleted due to the div it's in?
And that is behaviour that's considered good?

That's just it; it's not good. It's clearly a bug. But it's exacerbated by the fact that GOG decided to merge social media buttons with the wishlist and the two have nothing to do with each other. The Wishlist button should stand alone IMO.

Hehe, you're welcome. :)
