FEATURE REQUEST: Add interface for broadcasting different input to panes.
When in broadcast mode you often want to type something different in each pane briefly. It would be great to have an interface specifically for this. I imagine a keystroke like CTRL-Tab that cycles over every broadcast pane and then back to all. There should also be a toolbelt where you can define "broadcast variables" which would actually be an array of N values where N is the number of panes and sending the variable would send var[N]. (I hope that is clear.)
