I am writing this using the ‘classic’ WordPress editor, which has a column on the left of the screen showing all the areas I can work in, and a column on the right showing the things I can do before publishing. It all works well and I don’t have to search around for features.
The latest ‘improved’ editor has something called ‘blocks’, whose container must be clicked on to become accessible. There is no longer a left column and the Publish area is reduced and lacking Categories and Tags which were previously visible and are now hidden.
I (and I should think many others) will be using the classic editor for as long as it is available. See WP Tweaks, for example, and the negative comments from experienced users.
