Hey Marco!
We do have a simplified view for seeing more thumbnails on the same page at the same time. IMO simplified view + arrow keys can be nicer than trying to scroll through an infinite scroll page regardless of thumb size. Of course you can have a different opininion😃
Most of the time users are using the site to see if they would like to use an image as a wallpaper; the idea behind the larger thumbs is to do that job better; and that's the direction our main thumbnail presentation needs to follow.
Thank you for your input!
