So personally, my vision isn't the absolute best and I find the new background to have very poor contrast with the main elements on a page--making it harder to navigate than most sites. I just pulled open the inspector and changed the background to something darker (a lime green color) and found I preferred it. You mentioned giving people the ability to create custom shortcuts via a setting, it'd be nice to be able to change the background color via a setting. On sites that support it, I choose a dark theme as I find it easier to read.

Thanks a lot for the feedback.
