Unecessary binding on all IPs for websocket

[meepmeep]

I'm using browsh on a dedicated server, and it works great :)

But when Browsh is launched, it is binding on all IP for the websocket port (default 3334).

tcp6 0 0 :::3334 :::* LISTEN 1000 685834833 20873/browsh

Is it possible to only bind the loopback interface ? (or a specific one like the http-server option) I don't need to have open port on the internet (and yes, I still can block it with iptables, but it isn't the most logical solution).
