@leocg Thanks for the answer. Then I would like to leave a request as suggestions for future updates of the browser. As a regular user browser Opera, I really would like to see the individual color settings only the sidebar, at the discretion of each user!

@leocg I don't want the whole browser in dark mode, my eyes get tired more quickly if use it all the time. For me it was much more convenient when only the side panel was dark, as before. Now it stands out too much and annoying.

How to change the color of the sidebar to black? Only the sidebar, as it was before. Now I can only change the entire browser to a dark theme. Please make it possible to customize the color of the sidebar.
