Not sure im the only one, but like with Youtube, google and some other overly bright/white sites, i find it relaxing on the eyes to be able to use a dark color scheme and lay off the Screenburn a bit. Not sure if this is implementable, but would be nice if it would be possible
Until such a time that a new theme may (Or may not) be implemented, i highly recommend the Dark Reader addon for Chrome. Here is the default look of the site with it enabled: You can also tweak the colors to your liking etc. Here it is with the brightness tweaked a bit: Here is a link to the chrome store page for it: Dark Reader - Chrome Web Store There's alternatives for Firefox aswell, but you'll have to find those yourself if you need them
