Feature request: Nested/OR sorting

[rogalian]

Don't know if this is feasible or makes sense, but I'd like to sort by Series and Title, where if Series is empty the entry is sorted by Title.

Sorting by Series puts all the entries with an empty Series first, followed by the stuff that has Series filled. I'd like to have anything with a Series beginning "A" listed first, along with any standalone titles that also begin "A".

Nested sorts would be nice too - sort by Manufacturer then by Year for example.

Or even better - Series (Title) then Year. So that the DonPachi series sits in D, and gets ordered by year of release rather than DonPachi sitting at the end.

A cheap way to achieve this might be by populating blank Series entries with the Title (less the bracketed information)
