I assume you are talking about the Calendar Notes Editor?
If so, that editor is currently word wrapping the text so I don't see the problem or do you want to be able to disable word wrapping? If so, why would you want that? Doesn't that makes it more difficult to edit notes?
Also, maybe I should put all Calendar/Quotes/Notes in their own separate file. That way you could use any editor you like. However, for example the calendar notes file needs to be structured obviously, so I'm not sure if a plain text file is the best solution. Maybe an XML file? However, would that make editing it externally more easy?
