Seriously....this just boggles my mind and wondering where are the priorities and rational thinking with the WP core devs. Let's start by saying this:

- Sure it might be fine for "small" CSS changes, but what if you need more; you then have to add a plugin or use a child theme.
- Speaking of small, that is a very small space to work in if you have a lot of CSS to do.
- Let's just keep adding more and more and more and more to the customizer that should have been used strictly for theme options only!

There are so many other issues that are more important...like:

- Put some effort into a proper CMS editor that does NOT touch my own code I add to the HTML view. Stop stripping out my stuff.
- How about adding core ability to disable widget titles on a per widget basis?
- How about adding core ability to disable page titles from the editor
- How about adding RGBA capability to the customizer core
- How about letting us create our own "Post Formats"
- How about creating creating a way to assign templates to categories
- How about core adding capability to assign widgets to select pages without plugins

There's a lot more things that can be added to the list, but I'm sure others can do that.

The core is getting absolutely ridiculous with the customizer. I keep saying that it should have been used only for theme options and settings. Wasn't it supposed to be that to begin with so that themes did not code in their own theme option pages? Now we continue to see more core stuff and plugins being added to the customizer. How soon before we get the whole admin added to the customizer!
