I still use Screen every day. I tried to switch to tmux, but tmux's copy mode isn't as good as screen's. For example, in tmux you can't search case insensitive in copy mode, which is really a must for me. I think that's probably the biggest reason I didn't switch. Am I the only one who extensively uses the copy mode?
