Hello World,
Not sure if this was done yet.
A simple workflow to tag (via a spotlight comment) any Finder selected files or folders.
usage: tag <comment> -> will add <comment> into the "Spotlight Comments" field, making it searchable via Alfred/Spotlight.
(using Alt will overwrite all previous comments with <comment>, default is appending <comment>.
