I don't know, something like random switching between bag and stats (most humans check their stats from time to time).
Break handler while it's still running, sometimes let it go "afk" for 2-3 mins to simulate you grabbing a drink or something.
Faster trap handling (if possible?), seems like it prioritizes looting instead of setting up a new trap, doesn't look very human-ish.
Better movement while laying traps, for me it often goes from one square, waits, goes to the next and then puts the trap down. Instead of just instantly going to the correct square.
I think random camera movement are kinda useless, most people dont really rotate camera while hunting (I don't, atleast). I just chill at only use my mouse for setting up traps and such while watching my 2nd monitor. But I guess it could be beneficial, just don't overdo it.
