Also @webfactory how I did the colours of the code syntax is with a css filter hue.
It targets the #fancyeditordiv with this css:
filter: invert(1) hue-rotate(123deg) brightness(1.1) contrast(0.75);
You guys can maybe make a setting to play around with that ‘hue-rotate’ or even the whole filter css where the user can type/select/drag their own hue/brightness/contras/etc. in the settings to personalise it a bit more.
