If you're familiar with Wordpress, then you already know that Pages have an area to select a template while Posts do not. As well, archive.php and many other pages are handled by a default listing template. These are handled through custom theme development if one wants them to look different.
My question is, "Why?"
Was this simply a design decision during the early years of WP development? Why can the Posts page not also have that same template selection area that Pages has? Why can Categories also not have this selection area?
The answers I'm looking for are mostly from a technical perspective. I've looked through the code and I can't see any reason that posts, etc, can't also benefit from being able to select a preferred template. I also don't understand why having to do this for posts still requires an elaborate development process rather than a simple drop down interface available to pages that allows one to access templates that already work perfectly fine.
As such, I'm endeavoring to write a plugin that solves this issue, but I'm looking for technical caveats I may have missed from others who are much more familiar with the code than I am.
If you know of any plugins that already address this successfully, please add those in the comments as I'd like to take a look at their code.
