Oh how simple a lot of things around the writing and coding experience could be fixed in Gutenberg. But alas these suggestions have been ignored and rejected.

What has been ignored for years in the text tab of TinyMCE is now been accentuated by Gutenberg. If you ever looked into that space when it contained anything other than a trivial amount of content and HTML, you were looking into a field of thistles.

A lack of formatting, no colour coded syntax, a lack of respect for indentation, and a very small canvas made it a horrid place to work. If all this had been implemented the comment tags delineating blocks would have been less of an annoyance. In fact developing code mirror further for this purpose. Could have included the option to toggle the visibility of the comment tags.

Taking this a step further, having the option to de-block the content and returning it to a single classic block would also have helped smooth the adoption.

And a bit more flexibility for how we can arrange controls and metaboxes for things such as custom field groups, featured image, categories etc would also be useful for those of us who have workflows based on data entry and actions other than the content itself.

A little bit more carrot if you want Gutenberg receive more acceptance.
