Awesome: A window manager that gets out of the way

I don't know about him, but I like 180- or 260-wide terminals. It lets me do 2 or 3 80-width panes (tmux) or windows (vim/xmonad) which is enough buffer for line numbers, fold columns, and some room to spare. 80 is obsoleye as a full terminal width, but 80 is still one of the most common wrapping widths in projects.
