Djay Pro for iPad - A few questions

#1 Is there a way to sort my queue by things like BPM or Key or am I stuck with whatever the default sorting is

#2 How do I access decks 3 and 4?

#3 Is it possible to sample more than one loop at a time?

#4 Is it possible to bulk analyze my queue for BPM, etc. without having to load each individual track?

#5 Is there a full manual online somewhere that might have all this info?

Thank you in advance!
