I know we have available plugins with custom head and footer but they both inject extra JS/CSS to the head of the forum.
What I need is to add some code just before </body> closing tag. I don't want to request for extensions so I prefer to directly hard code it. I don't mind it will disappear when I update the forum (it's not going to happen anytime soon anyways ? ).
So without building plugins, what's the quick & dirty hack to achieve it? Which file in codebase is responsible for it?
