Some type of automatic function to make all content items to items in content templater.

Thanks, I get your point, but I don't see it working very well.

The way Content Templater works is that you create predefined content and settings per template. A normal article does not have all those possibilities.

Also, a lot of websites have hundreds of articles, which will make the dropdown impossible to work with.

And Content Template is not made to only use in or for articles. You can use it for every content item with an editor...
