Man, this would be so much more intuitive as a command line tool that either generates a HTML file with the summary, or a CSV file with filename, focal length. Dragging thousands of photos into the browser window seem very sketchy (OK I just tested, Vivaldi doesn't like me dragging dozens of files onto it, I can do 2 files, but if I try dragging about 20 files it just loads one of the images, replacing the page).
I can imagine a CLI wouldn't even read the entire file (I have 15MB heavy images), just the few KB's at the beginning to find the Exif tag.
