In zmud you have a split screen scroll back to read long text in a static window while still being able to see incoming text in the dynamic window. Do cf players using mushclient just live without this feature? I feel like it is a great/advantageous feature of zmud and that you'd be gimping yourself by not having it.
I know the mushclient creator made a lua pop out window to try and emulate the feature but you lose the text color formatting of the mud in the process so I don't count it as equal to what zmud gives you.
