I use WordPress in two ways, as A developer and as A normal blogger.

As A developer, who use WordPress to create specific website with many and complex functionalities, I prefer easy access to FSE, which is accessible from any single post editor rather than on seperated menu like that of Elementor. I need to be able to save the current edit mode to affect the current single post, or as a template to the whole single post, or reusable template.

However, as a normal blogger who just need to write content, who don't know anything technical about templating, I prefer that this FSE editor far or hidden from my sight because if I spot that, I will try to click that, and get confused.
