The below is a rant related to a theme I was trying to get work, but really in trying to figure out how WordPress itself worked. It's not even as intuitive as it should be.
Now here's the rant that explains the problem, that the Developers need to change.
Boy, crazy stuff.... I was trying to figure things out "intuitively", creating Category's, child/parent categories etc. While it all actually worked, turns out if I want to use a "Template" for a Category, I can't, Pages have to be used, hence the non-intuitive instructions in your documentation on creating a page, making it parent, creating other pages, making them children, all through the custom fields you've created, using ID's etc.
Really the Category section should have the same post/page editing ability as Pages and Posts do, and also be able to "select Templates", and then the Pages should have the ability to select a Category to be child under if wanted.
My gosh, so intuitive and simple. Turns out though, one can only use a Template on Pages. Although in theory I could change the default Category Template, but that's getting into the code. But, then you still have the issue of the pages not allowing you to select a Category, nor Posts to be able to select a page.
So, it all comes down to the reality that I can't set up the site like I was thinking it should be set up, and must follow your instructions related to creating a Portfolio. If I didn't have to use a Template for my folio, and just used the blog settings, it would have been easy creating child pages, assigning posts to the Categories we wanted etc. But instead, WordPress are morons, and haven't discovered this, and so in order to do things like a Portfolia, we have to enter post ID#'s manually, etc. What a pain. Especially, if I have other people creating content, I will have to train them on how to do the ID stuff, instead of just being able to select Category's and Pages to post it to. Man, terrible I have to think about this so much..... :(
Anyway, just ranting. Someone should create a Plugin that has all the same functions as in a Post & Page and add it to the Category section and for the Category's to show up in the Page section, so you could Child pages if you wanted also.
I'm pretty dumb in this technical babal, but this is just common sense to me.
