I think it would make perfect sense for us to have a comic infobox template like we do for episodes, with info like who worked on it and such over there instead of the main article. However I've been trying to build one for like a day and for some reason it just isn't working. I'm not sure if they've killed some old tags I was used to or what.. I even tried copying and editing the episode template and I'm sure I broke something.
It might help not to use the visual editor. It's imprecise and can introduce mistakes that remain invisible. It's better to edit the source raw, and use preview as needed. But editing templates can be all the trickier because you're not just editing appearance—you're editing logic, not all of which will necessarily display itself on preview and will have to be tested. It may be a good idea to set up a sandbox page to temporarily test your templates with their different parameters.
