A couple of things that would make NPC creation a little easier:
1) display the breakdown of "weapons/armour/magic/etc" value (p 454, Core Rules) when you create an NPC rather than a PC.
2) Be able to sort magic items by price (or any items, really). I know sometimes I'll just want to scroll through the list and pick a magic item I may not have used before - something a little flavourful for that particular NPC, but it'd be nice to keep all the affordable items near the top.
Keep up the good work, guys - as always, HeroLab is perhaps the single most useful application I've ever used!
