In addition, it would most likely be me that would implement such a feature, which I'm not going to do. I'm thinking of making a template function to return the path segments rather than something so specific, which would permit the user to construct the path however the person wishes.

It doesn't for me. I suspect that something got changed when you entered the template.

Is there a way to modify the code to place the file in the {Author} folder? This would really solve the issue for me .

This template adds the author used by calibre in the library, and is slightly more robust across operating systems.

python:
def evaluate(book, context):
	import os
	from calibre.library import current_library_path

	fmt_metadata = book.get('format_metadata')
	if fmt_metadata:
		for v in fmt_metadata.values():
			# A calibre format name is three section, author, title, format.extension
			# We want to return author/format without the extension
			p = v['path']
			r,f = os.path.split(p)
			format = os.path.splitext(f)[0]
			r,title = os.path.split(r)
			r,author  = os.path.split(r)
			return '/'.join((author, format))
	else:
		return 'title - author'

Using the above template, the book

saved in the library at

"C:\CBH_Data\calibre.git\Library.test_small\A B\Unknown2 (foo) (1313)\Unknown2 (foo) - A B.epub"

generates the path

A B/Unknown2 (foo) - A B

On my Kobo Libra 2 the book is stored with no doubled extension at
