Is there a way to get the interactive markdown editor to do basically what a word processors "track changes" does.
For example, the editor is pre-loaded with the following text.
The small brown dog jumped over the lazy fox
Then the user changes the text to the following:
The small brown dog jumped under the lazy fox
I want the following to be displayed:
The small brown dog jumped
overunder the lazy fox
Does pagedown (or any other interactive web-based markdown editor) have such a feature?
It's not fully integrated into your editor, but you can get this effect with some of the javascript diff implementations. jsdiff, for example, does what you're describing: http://kpdecker.github.io/jsdiff/ . Xindiff also does this.
