Please restore classic code editor.

Completely changing the editing process without furnishing complete documentation is irresponsible. The option to use the “classic” editor offers visual/code options, neither of which emulates the classic editor. For one glaring example, the visual mode offers an option to insert a media file (uncleverly disguised as an icon instead of the previous Add Media button) but the code editing option does not. At the very least, please restore an Add Media button or icon to the code editor for those of us who were quite happy with the classic editing options.
And if you expect anyone to use the new editor, please furnish proper documentation. If it is already there, tell us how to find it!
