It was one of my requests; I asked here about the ability to
cache the book count and also brought up the idea of just hiding the zeros entirely.
Saved searches can sometimes be very complex. For instance, I use this one for "books to read again" (mostly books I haven't read since last year or stuff with no last-read date, but it excludes a bunch of stuff too so I don't get stuff like game manuals or books I thought were crap):
Code:
(#read:true AND #lastread:true AND #lastread:<365daysago AND (rating:">2" OR rating:false)) OR (#read:true AND rating:false AND #lastread:false AND (not tags:"=.Documentation and Manuals" and not tags:"=.Magazines and Periodicals" and not tags:"=.Nonfiction") AND not #fanficstatus:"=In-Progress")
And I wouldn't be surprised if other Calibre users have saved searches that make mine look mild. So having Calibre calculate the number of books that fits that every time you edit a book's metadata would make it chug a bit. So saved searches are brought up on-demand.
