There's a pause button (you can even set it in the key configuration screen), but like "loot all" (spacebar) it's simply broken at the moment.

I know if I make a water surface on the ground, enemies don't get wet, but they do if I use knockdown on them. Not the same with water and burning enemies? If so, yes, that should be added (on knockdown, not just walking over it).

Well, I am somewhat suspecting they will remove keys from ALT highlight. That should make lockpicking way more valuable since most of those keys are almost impossible to find without the highlighting, but with highlighting now you can find all keys so easy lockpicking is indeed worhtless.
