Content Preservation 

Compatibility with the browser's back button.

Don't you hate losing your edits?  It is so easy to accidentally browse away from the page you are editing (eg by hitting a back space key or button).  And then you have lost all your edits.  Unless you are using EditLive!.

For a demonstration you can try this in any browser:

1. Load the EditLive! 6.0 Online Demo
2. Type some text in the editor (it will be tracked using track changes).
3. Click “Back” in the browser.
4. Click “Forward” in the browser.
5. Note that all your content is still there.

Then try the same sequence with any other online editor and see what happens.
