I honestly don't know where to put this, as one could argue it to be a Policy or Technical topic (or even both), so I'll just put it here, and let the mods decide:
Using the Marvel Database wiki as an example, when you click the Appearances link in each character pages, you'd be presented with a Category Page listing all the character's appearances, as expected (even with the DC wiki). But beyond that, here is where they differ: The Character Appearances page for the Marvel wiki has, right at the top, an expandable (& sortable) list/table, that shows all the character's appearances CHRONOLOGICALLY, using the issues' Publication data. It's extremely useful when you want to find & read issues for a character (say Gwen Stacy/Ghost-Spider), as they were originally released/published. Wookiepedia has a similar-ish Appearances list (though not as clear and/or convenient).
So my question is: Why doesn't the DC Database wiki have this extremely simple, yet extremely useful feature/tool? Is it simply a Policy decision to not do it, or is it a Technical one? Or perhaps some other reason altogether?
Anyway, thanks in advance for the answer. And if I could persuade the Admins at all, I truly hope you would re-consider this feature for inclusion. As it really helps fans like me, a lot.
