I have the same opinion. There must be a more normalized way.

Yes. But we have to take care of the indentation... maybe we could just save 
the indentation text like "\n     ".

Interesting thought... so you mean making the the changes in the node tree and 
then synch the text editor. I see some disadvantages though:
1. in VPL you'll have to rebuild all the tree when undoing.
2. you can't have user defined indentation.
3. what holds the document is the tree not the text editor. So if count on the 
text to make changes to your document you'll soon will find some limitations 
like the first point.
I don't think this is a good approach.

It would apply the Quanta formating. See above. Eric want's custom indentation 
and I would like to implement that so I think it would be more an advantage 
that the opposite.
