Not that soft wrapping of text at a specified column other than window width is something I do, but I can think of a few reasons why one may wish to avoid resizing the window, particularly so that it’s only 80 columns wide, to accomplish the desired effect: So that the menus and tool bar aren’t adversely affected.
If I wanted to achieve custom soft wrapping myself, I’d prefer NOT changing my window size specifically because I prefer having NPP open in the same custom location and size every time I run it, and I’d have to reverse my window size changes before closing NPP in order to maintain that.
One could also increase the zoom level until the desired wrapping occurs, though that, too, would have the potentially negative side effect of reducing the amount of text visible at a time.
