Yeah I know, I'm already using that method to separate my books and music, but it would be nice if I could just press the big round button three times to play all my music, especially while driving...

The player has an option for "Ignore as child", which if you set it on your Books playlist would do exactly what you're asking. Sadly, the tickbox for that option in emplode is missing .

This is fixed in 1.1.

Where does the name 'Wendy filter' come from?

From Hugo's then girlfriend Wendy; the feature's first intended use was to pretend, whenever Wendy was in his car, that he didn't have any Carter USM tracks on his player. The feature took so long to implement that Hugo's now not seeing Wendy any more, and I don't believe his current girlfriend has any great objection to Carter USM, but the name has stuck. (Tony, should this be a FAQ? Perhaps when 1.1 is actually released?)
