[Answer]-How do I turn on autosave for TinyMCE in Mezzanine?

I created my own autosave plugin for TinyMCE, I can’t share the code due to office rules but what you need to do is use JavaScript or jQuery and set a particular configurable interval on which an AJAX call is made to the server by sending the content of TinyMCE (using tinyMCE.activeEditor.getContent) and save it at server side.

You can also add a button for this so that before making an AJAX call just check the status of button whether it’s enabled or not.
