INB4: This is a really minor, petty suggestion.

Occasionally, when I try and navigate via the toolbar, I accidentally click one of the "?" and it opens up a help page in a new tab which is an (extremely inconsequentia) irritance.

It would be nice if we could have an option to turn off help in the options menu, so the question marks don't even show up.

It's a small UI tweak, but the type of thing that will/would/does a make a difference. 

It's rare that most users will click on the help guides outside of while they're actively learning. So having it as an optional toggle would seem a good call for anyone on mobile devices (or even just old and bad with a mouse).

I agree. As Setanta said, most new people are learning as they play so there's no need for the wiki to not be an optional thing.

i'd concur with this.  simple enough, but handy as hell
