Is it possible to make Hachidori only detect files that are in a specified directory? I know there's a way to omit certain directories (blacklist) but is it possible to disable all directories and only enable ones the user chooses (whitelist)?
Currently, it's only possible to blacklist directories, but I can add an option to white list directories in the future, if this is what you are looking for.
You can specify what directories to ignore in the Exceptions preference pane.
