How to display tagged files inside hidden directories?
Not exactly what I was looking for, but here is a neat trick that satisfies most of my needs.

Create a new directory, hide it via chflags hidden directory, deposit tagged content in it.

Finder will cooperate with us and display all tagged content.



file is tagged dev and exists in a directory hidden via chflags. I named the directory dev as well for convenience, but this is not strictly necessary.
