Please could add a toggle, DIVI and Admin Columns support?

Hi,
Thank you for the great plugin!

I noticed that the Theme Customisation page side menu is still bright white.

Is it possible to add a quick toggle to the admin bar in the Dashboard, please? This would be a nice timesaver to avoid having to leave the page your working on, go to profile to disable or re enable the dark mode.

DIVI Theme Options page is blinding white background and Admin Columns some dark text on the dark mode background which is often difficult to see.

Many thanks!
