Oh wow, what a funny coincidence. I hadn't visited the site in a couple of years but someone linked me "Front and Center" yesterday, so I saw the icon for this app and had no clue it had only appeared there maybe hours earlier. The idea is not new, of course, and I've written one of these (for Linux, with hardlinks) years ago but in the end just deleted all the duplicate files in my mp3 collection and didn't touch the rest of the files on the disk, because not a lot of size was reclaimed. I wonder for whom this really saves a lot of space. (I saw someone mentioning node_modules, had to chuckle there). But today I learned about this APFS feature, nice.
