Why does the hash have 8 digits?

Hey, I think your plugin is great. I was just wondering why the hashes have 8 digits. I mean 4 digits would suffice for 60k files in a directory, with 8 digits it’s billions of files. A funny side effect is that toggling a colorizer plugin colors the hashes, because they are recognized as RRGGBBAA values.
