Is it possible to see long lines with line breaks?

Yes and no. Breaking lines “inline” in the standard view is not supported – it has too many impacts on scroll behavior, line count calculation etc…

But there are 2 ways to see also long lines completely:

1. The current line is displayed in the “Line content” view (one of the output windows).
2. You can enable a “full line popup” window in the view’s local toolbar. If that is activated a popup window will be displayed by moving the mouse to the “non-content” area (line number etc.) of a line.
