This is reflected in my survey answers, but I want to quickly elaborate a little since this is personally my #1 feature request above all else; NPC orders are mentioned, but not hot-keys. I would really, really love to see a robust NPC command system with hotkeys, pleease!
edit: I actually posted a thread about exactly this a little while ago, but it got no attention; NPC command hotkeys
glad to see this mentioned in this survey though
