Dear Jonathan and Stefan,
Thanks to you both for answering these things it is truely really appreciated.
I was thinking of changing all my scripts to explicitily do what is
intended rather than relying on any "current behaviour" in case you
did just what you are saying Jonathan.
I can already see that some of my earlier scripts may not work under
recent improvements like \n working now where I was previously looking
for the unicode usage. This happend ot my itemList.js script that
produces a list environmentm using the drop down box dialogue to
choose the environment type.
I am in the middle of a writing project and simply make scripts when I
need something and share any of the generic ones on Stefan's Script
261 Issue http://code.google.com/p/texworks/issues/detail?id=261&can=5
in case they are useful to any one else, or a base for imporvements on
what I have done.
On the constants, are we able to run another QTScript from QTScript? I
noticed a command that looked promising but was not sure what to pass
to it as it was looking for an object not a string filepath?
If so would variables in a header script run first be available to the
calling script, or would they pass from scope/memory when the script
called script finished?
If such constants or even functions could be loaded in like this, I
was thinking that I would be prepared bit by bit to try and make up
the constants lists as things came a long (dialogues etc) so that
there could be a library perhaps of useful scripts that could be
called for QTScript, and if any one else wanted to adapt them for .py
and .lua there would be a starting point hopefully easily altered.

So perhaps this will change (which would mean that existing scripts that INTEND to display a result by returning it will have to be changed to use TW.information or similar).
