I absolutely love the night mode. I was very surprised that it was added but it shows Team Steemit is listening to our requests. (I commented asking for a dark mode on a recent update, looks like a bunch of others did as well!) However, when navigating to a specific comment link on a post, where it is supposed to be highlighted, it currently looks like this: 
As you can see, the comment is totally invisible due to the highlighting colors chosen, so maybe change the text of a highlighted comment to black, or else change the color of the background highlight? Just wanted to bring that to attention. Thanks so much for all your hard work!
