Feature request: Inverted colours

The "Submit an idea" button doesn't work on the Edge Code page, so I figured I'd request here.

Due to eyesight issues (Kerataconus), I've set up Dreamweaver to use a darker colour scheme for code colouring. I'd like to see an 'invert' feature or a high-contrast feature for Edge Code. I realise I can invert the screen colours, which helps in Dreamweaver, but my eyesight issues means that if light colours are on top and dark colours below, I get a trail of light that hangs down over, meaning anything in the first 10 or so lines is just a white blur, so a true invert / high-contrast (still retaining the code colouring, as I love that feature) would be fantastic.
