Other editors I have used DO allow existing text documents to be opened and viewed in word-wrap mode. So in Multi-Edit that ability only exists if the text document is first produced by the app itself? Or, are you saying that word-wrap mode only applies to content generated "during" the Multi-Edit editing session?
As I noted earlier, the text documents I am trying to view are very simple and clean. Frequently I look at code headers and comments from other authors which (for whatever reason) are sometimes very long in line length. What I am trying to do is to avoid installing a separate text editor for the singular purpose of viewing certain types of source docs in word-wrap mode.
