Matt Mullenweg, creator of WordPress, gave an address in Belgrade about Gutenberg. He discussed that future installs will ask users to choose between the Classic Editor or Gutenberg for text editing. This is one feature of Gutenberg that I have reservations about.
My first reservation is the ability to copy and paste text. In the Classic Editor, I can copy and paste text from a Word Doc to a post with ease. With Gutenberg installed, I get extra paragraphs or no paragraphs at all. Additionally, I worry about the ability to add HTML/CSS code into a post. I’ve modified page layouts by adding CSS styles and tables. Gutenberg has yet to adjust for plugins that fall under the “Extended Settings” field. For example, I use a plugin called WP Multisite Crosspost. In a multisite environment, I can create a post and have links show up in other blogs. It works fine in the Classic Editor, but not in Gutenberg. I also cannot add links without reverting back to the Classic Editor setting.
What I want and hope is that Gutenberg will not give an “either/or” option for how users write their blogs. But, I recognize that may not be the direction WordPress will want to go. WordPress seeks to increase their user base.
