I would like the theme colours of the browser to automatically match the colour scheme of what is currently on the desktop. Similarly to the "automatically pick an accent colour from my background" in the Windows settings for the Windows colour scheme or how you can set the Opera browser wallpaper to match the current desktop wallpaper.
I have a desktop wallpaper that automatically changes colour depending on the time of day and have my Windows accent colour match it. It would be amazing if I could do the same with the GX browser to complete the look. Opera GX is all about user control, customization, and creativity and this feature will enhance this even further. I'm sure many other people who have rotating wallpapers will greatly appreciate this small but fun and pro user feature.
