Some click actions could use an option to enable player sneaking.

Yea, certain hotkeys. Plus, it'd give me another excuse to use integrated tunnels more :p
I can see why it'd be hacky, tho.

@moonheart08 Can you make a separate issue on this? It's an interesting idea, maybe I'll have some time in the distant future.

Would pushing/holding buttons even be possible for a fake player? If so, that'd be nice too. (Some mod items have secondary abilities triggered by pushing keys)

@moonheart08 Certain hotkeys you mean? In theory that would be possible yes, but practically this would require a lot of hacking, so not something I plan on doing anytime soon.
