Darktable, by default, has a very simple and light view for browsing images.
As you can see, it’s very sparse. There’s nothing to interfere with viewing the images, which is the base philosophy of Darktable.
The problem is that I don’t like it. I like to see what’s what. I have set the my own display of what I want to see. But to see it, you will need:
Press on the * at the top right of the lighttable
Select either overlay on mouse hover or permanent overlays
