I’m using Atom to write HTML emails (yay). These include long URLs, so I have Soft Wrap turned on.
Note how the line gets broken in the middle of the word “Final”. There are lots of better places for a line break.
When I go into my Settings, there’s an input box for “Non Word Characters”; these characters define word boundaries. It seems to me that it would make sense for Soft Wrap to break lines at word boundaries instead of only at spaces.
