Use case or problem
I like to start new clusters (say, a textbook chapter) in a separate directory.
I like to do some work there, and when I am happy enough, I put it into the big folder with all the other things.
Before that move, I’d like to add some tags to the front matter for all the files in the directory. (and create the front matter if needed).
Proposed solution
Right-click on the folder in file explorer, and “add tag”, type the tag to add to the files in the folder.
Current workaround (optional)
Do it by hand for each, or write a script. Arduous and error-prone at best.
Or make a template (but it’s necessary to get that right before doing any of the work!)
