On PC on 16:9 monitor there is still a good amount of place left on the lefts on rights of the actual text, which looks a little bit boring. Maybe it can be filled up with community made art, and I personal would not have a problem with ads being displayed there. Of course for the first idea there needs to be enough community art (preferably made in Armory), or maybe pictures of scripts or logic-node setups.
I do not know, those white spaces look boring.
Damn it, this space doesn't exist on mobile devices, so that's a bummer.
