title: How would one make an Xcode style console window?
body: <p>I am making a Haskell editor with Cocoa, and it would be useful to support some in-application text output. Even better would be supporting some text input.</p>
  
  <p>Xcode does all this in its console, which looks like it might be an NSTextView, but not sure if somebody might have done all this before.</p>
