This toggle option, previously talked about
I think this one really needs to be updated. I heard about a Valve statement saying that they won't update a feature that is used by less than 2% of playerbase. But nobody will use it in its current form, its just not viable and an obvious handicap.
Also it could use some rebranding, by its current name its not really obvious what it does and also its disabled by default. AND it doesn't work in demo mode, meaning that you if you try settings in demo this one will not do anything at all.
Valve, please fix.
