This shouldn't be hard. I would like to edit some raw text in your web editor and I want to keep each paragraph on its own line. The editor is aimed at code and so it doesn't include line wrapping. But I would like to use it.
The CodeMirror editor that you use has a boolean that can be set (lineWrapping) to true to turn on linewrapping. Could there be a button that does this?
A super-slick option might be to let each user set up a JSON block for configuration. But that might add too much to the job and it might be overkill. I'm not sure how many people would want to tweak some of the other parameters.
