Thank you! Reading that comment was actually what prompted me to make an account just to reply that, and then when I did it was gone.

showdead is essential for Orange Reddit but it will show downvoted comments in unreadable light grey on light grey. So you probably want an users CSS (e.g., with Stylus) like this (italic and the particular color are to taste, of course):

    .c5a, .c73, .c82, .c88, .c9c, .cae, .cbe, .cce, .cdd { color: #222; font-style: italic; }
