I did it for myself, but maybe someone else will come in handy, who spends a lot of time in the admin panel, editing templates. This plugin converts the control panel to a dark style.
The plugin has color settings. Also, a separate setting was made for the design of the template editor (CodeMirror) with a choice of 10 styles. All of these settings only change in master style, so developer mode is needed to change.
Make your Admin Control Panel have Dark Theme!
