The Bytes forum is not specific to Gator Country and not a way to make suggestions for improvement. I would suggest that you might want to post in the Help Forum and make the suggestion. I will refrain from making a snarky comment that if you want 'dark mode' just spend a few minutes in Too Hot as that would possibly offend someone.
While its dictated by Bytes they may have a forum widget of sorts you guys could use. Have you looked into all the bells and whisteles? I have Dark mode for almost everything lol.
