your dark theme suck !
did you ever use it ?
opera is good apps but dark theme need to be improved !
when i click on dark theme in the option menu,
i expect "dark" in all page, to browse the web in a dark room,
safer for my eyes
i don't ask to you to do all webpage online,
i use an extension to complete dark browsing "dark mode" for the webpage,
i don't expect you to doing better than that.
but if you have time to merge this extension into opera, why not...
BUT my point is your dark theme don't do dark in :
-right click menu
-in speed dial the folder are still in white...
-and important too, when i load another page, whatever the page, can be the speed dial or online page, for a second i have a white empty page of loading...
should be a black empty loading page, because it do flash in my eyes, everytime i click
i mean, even microsoft edge have a dark theme doing dark in donwload page, history and more ...
this is important to me and very annoying
please check your dark theme
the perfect thing will be to allow users to change the defaults colors of all menu, and page, inside opera
here some ref to help you :
