I have no idea who would consider this 'new' (it is actually not new but fortunately did not replace the existing presentation of this list) way of showing the list as floating window, as a good idea.

This floating window lack most of the information and is lacking basic interactions, like skipping in videos or switching between video and pictures or switch through pictures.
So all I have to judge if a game looks interesting is a video I have to watch from the beginning to the end and then still have to switch to the shop page to get basic information such as if the game is singleplayer or multiplayer.

Now it seems the stickers for the autumn event are only granted when using this 'new' but worse discovery queue.

In order to change my complain into an idea: I suggest to get rid of this 'new' but worse discovery queue presentation completely.
It is just annoying to use and to think of this useless 'feature' made it even to the end users.
