Seriously...I hate that kind of advertising under my games /:
Steam doesn't shove their catalog right under your nose when you are on your owned game page.

I agree absolutely. What makes it particularly annoying is that they moved information relevent to the games we actually own off screen to make way for it.

Edit CSS

You could explain which CSS elements to modify in the current GoG *.css files, and which *.css file to modify.

Please Gog, remove this ad.

GOG's not a charity. They're part of a publicly traded, profit-maximizing company. So you are going to have to suffer thru the world's least intrusive ad as part of this terrific free app they offer you.

I have an advertisement in the page of a game in Gog Galaxy that I bought on gog, isn't it ironic?
