theming idea is really bad

[ghost]

current approach "logically forces" users assign specific colors to a set of colors. we all know that it definitely isn't a correct way to theme an app!

themes {
    nord {
        fg "#D8DEE9"
        bg "#2E3440"
        black "#3B4252"
        red "#BF616A"
        green "#A3BE8C"
        yellow "#EBCB8B"
        blue "#81A1C1"
        magenta "#B48EAD"
        cyan "#88C0D0"
        white "#E5E9F0"
        orange "#D08770"
    }
}

all other apps apply the "label-based" theming approach which is much better and explicit to customize, i.e:

themes {
   nord {
        main_fg "#D8DEE9"
        main_bg "#2E3440"
        
        statusline_fg "#D8DEE9"
        statusline_bg "#88C0D0"
        
        current_selected_item_fg "#D8DEE9"
        current_selected_item_bg "#A3BE8C"
        
        // other elements and parts for ui
        // ...
    }
}
