Variator, from Scriptographer
A lot of the Scriptographers were artistic coding, but some of them were crazy UI improvement.
The variator is a "transform each" with random. It should be a basic tool. Adding some randomness to any bunch of items is a a really tedious process at the moment. You should figure out a tool.
Ho wait ! It already exists, you should just copy it : https://scriptographer.org/scripts/general-scripts/variator/
Thank you in advance, even if i don't hope too much about this feature request ****, since you still didn't add keyboard shortcut to rename the layers...
