I thought I wouldn't like the new design, but what I can I say? I looove it! And I'm not gotta grow tired of it this soon. But...There's something that bothers me.
I'm used to sleeping every night. (Who doesn't?!) The next day, I come and wanna check what questions I missed. I'll upvote the interesting questions, edit some of them and other questions, downvote @santiago's questions1, downvote the very poor ones etc. So, as I don't wanna create a tl;dr version and I wanna make the story short, someone like me would find a different color on the titles of the questions that I visited (i.e. the visited links on the questions tab with another distinguishable color from the questions I didn't visit) very very handy.
As the default design of betas before graduation had this color difference, I know how useful it is for a contributor to know what stuff he'd dealt with and what stuff he hadn't yet. I'd like this implemented, please? Hope I'm not too late and the design team will respond.
I also tag this discussion, so if anyone had an idea about what color would be better, they could chip in. I myself am not recommending a special color, but as user experience experts, I know the design team would choose something bluish.
