   It´s like a real time inspector and much, much more.   use the getroot() button,  or write that on the text field :  getroot()   or   getglobals()  will show you everything that is loaded on the newton.

  You have to use the :setValue(frame,'slot,data)  function to change a text in a view and have it display the change inmediately.   You can also send that view a :dirty() message and a :refreshviews().

  I'll take a look at your code and get back to you.

  Things that are stored in a package are read-only.  If you want to edit them,  you have to clone or deepclone them.  look for those commands in the manuals.
