Better text editor

Is there any way to get a better text editor integrated in Navision?

I am thinking about one that offers features like:

* Coloured code.
* Line numeration.
* Overview of all code related to a report, so you don't have to check sections and data items separately.

The code viewer in MSB Developer's Toolkit has most of these features, but it seems to only be a viewer and not a proper editor.

I am new to Navision so please excuse me if this is a stupid question.

Any help appreciated.

Cheers.
