DB website folder thumbnails - plain blue please - no photo collages

Good afternoon, please, I would like to know how I can see the folder covers with the image of a folder again from the computer. I don't like AT ALL that when I open my Dropbox and see folders with collages of images or files inside. It is really uncomfortable to see that many files, it confuses and confuses more.

Before it looked cleaner and tidier to enter and see all the folders with the same cover which was the image of a folder. And the strange thing is that I get some folders like this and others with the update, which makes exploring the interface more uncomfortable. I hope I am explaining myself and that you please provide a solution.

I don't know if that's how I explain myself better: I CANNOT stand photo previews. It's much harder to navigate through folders now because I'm distracted by images instead of just looking at the folder names, which I also name in a way that tells me what it is without having to go into the folder. Many people who use Dropbox are very visually oriented people, so the chaos of photo collages has a greater impact. It definitely disrupts my workflow. Thank you in advance.
