I’ve been doing some additional testing, and I’ve discovered that Gutenberg will make it impossible for me to blog the way I currently do. I include a lot of screenshots and code samples in my posts, and Gutenberg is not allowing me to format posts as I do now.
Not only does Gutenberg force more clicks of the mouse to do standard tasks when creating a post, it is also stripping out the majority of the formatting I have in my posts.
As I use a lot of images and code samples, I write my posts in Notepad++, for word completion and syntax highlighting, and then paste into WordPress. When I do this, it either strips out the HTML formatting or removes it entirely. The same happens whether I am pasting into a normal block or an HTML edited block.
The posts I’ve tested with have ended up unreadable due to this.
While I can upgrade to WordPress 5, I can only do so if I also install the Classic Editor plugin.
