Hi, I would like to know what is today the simplest method for set-a-finder-label. Reading in the forum I found an apple script that works and a plugin "Set Finder Label" that I did not understand how it works. Since they are outdated discussions I hope there is something even simpler.
Simplest is probably using the Set File Attribute-action (under the "File"-category) and using either tags, or tags (add) to set your Finder labels 
Thanks Martijn for directing me to the new feature. I searched the forum and found a post, linked below, where JMichealTX also provides the example. super!
