Earlier quoted context omitted.
Looking forward to drop shadows and brushed-metal in tmux, which you shall promptly post. Also fullscreen exposé-like dashboard with previews would be nice.
Funny enough, iTerm2 has expose for its tabs, but I never use it. It's just not how I work. Drop shadows are not needed, since in iTerm2 or tmux the entire active windows is brighter and all others become slightly greyed out, so you never confuse what has focus. Bushed metal on the other hand is not something I want or desire.
... which means nobody else needs it, right? :)
