I have problems like everyone else with the new editor, except that my main issue is editing existing posts.
1. Why I don’t want to use the new editor, in order of importance:
– it doesn’t take up all of the screen estate, only a narrow column in the middle of one of the two of 24″ monitors I use to work with text.
– it meddles with my HTML code. I have many “tl;dr” (very long) posts (not here, on another blog) which I like to format with empty lines in order to facilitate editing.
– it is buggy (read: non-functional) in my browser of choice (experimental Opera running on Ubuntu). Now, I don’t ask WordPress to adapt to my needs; but if everything else works fine with that browser, why would I want to switch to something I don’t like just because one beta feature on one site doesn’t work?
The first two problems make the editor unusable; the third can be circumvented (I could work with WordPress and WordPress only in Firefox, for example).
2. How to circumvent the new editor
Of course, clicking on the little pencil icon on your blog post takes you to the new editor. To use the old editor, the only way is to go to “Dashboard” -> “Posts”, search for the post you would like to edit, and click on “Edit”.
3. A better solution
Another, better solution would be to add a link rewrite plugin. The link to the old style editor looks like this: https://yourblogname.wordpress.com/wp-admin/post.php?post=1234&action=edit
Since the link to the new editor looks like this:
I think that a regular expression rewriting your links (for example, a simple bookmarklet) should do the trick. Essentially, you would catch the regular expression “https://wordpress.com/post/BlogIDNumber/(%5B0-9%5D*)” and replace the link by “https://yourblogname.wordpress.com/wp-admin/post.php?post=$1&action=edit”.
The code below is untested and you should use it on your own responsibility
Replace “yourblogname” by your blog name (e.g. “logfc” in case of my blog); replace “YourBlogID” by your blog ID. Add a bookmark that contains, as reference, the above code. Clicking on the bookmark should replace all “new style links” by “old style links”.
Here is an example screenshot from Google Chrome. You see that in the field where you would normally put your URL (http…), you enter the above code (except that you replace “YourBlogID” by the actual ID and “yourblogname” by the actual name):
The downside is that you will need a bookmark for each blog that you are writing.
