About that _close/done/ok_ button, currently the advanced UI is implemented
as an `iframe` inside `nfShell`. The close 'X' button is a part of to the
`nfShell`. So for closing down the advanced UI you need to close the `nfShell`
too. I guess it can be done by traversing to the `nfShell` via the standard
`window` object. Is this approach ok? Since it feels, it introduces another
coupling element.

>
> For the scripted processors it would nice to add an advanced UI with a "code
> editor mode" that would provide some very useful features when typing code:
> - indentation
> - code highlighting
> - do not close the window when hitting enter
> etc
> The use of codemirror.js (as already done for EL auto-completion) sounds like
> a good option.
