@chaley,
If someone chooses to autosort a grouping by Author, would it be possible to (silently) actually sort by Author/Series/Title. Would there be any harm? Based on a lot of the early work with metadata plugboards, I think it's probably a common sort preference and it would be very convenient (
especially for me 
)
Just to be clear, I'm not suggesting that choosing Author from the standard Sort button would do this (
even if I'd prefer it this way), just the autosort.
