Right, if we really wanted it to, we could have the option to toggle off the logo, but the build info would always show up (no option to toggle off).

It would show up by default when taking a screenshot, but have a toggle to turn it off in the Options menu.

Considering what @Stan` just said (I'm in the same page of wanting to know the version, particularly in a state of constant development), what about having the option of not to show the game's logo, but always show the version below it? I'm in favour of the rest of what you said.

Just to be clear, I'm not strictly against it. My point is that you can't assume how people will take screenshots. And so if the presence is conditional then it might not be here  

That's cause all mods have to be signed prior to being visible and compatible. Each new version has to be signed.
