not a fan of bright white background ... an option to switch to white-text-on-black-background would be sweet.
Keep up the great work, guys!
Thank you for propostion. We do not plan to build that feature. However, meanwhile you can simply use a browser Extension to achieve the same result. I just tried https://chrome.google.com/webstore/detail/invert-page-colors/hjhdnhiofjddcapmffbllcpaodjmdphn and it works great.
