Build an Email Buider using Unlayer Editor

I need an unlayer email builder development for personal use. I want something similar to the one at [login to view URL] but will settle for the code found on Github at [login to view URL] I have the actual editor working on my localhost but I'm having lots of trouble creating SAVE, IMPORT and EXPORT buttons. Please see [login to view URL] . They have directions on how to do this in their documentation, but I'm not able to implement this. I ultimately would like to have a working way to use the editor on my local host or a remote host so I can create, edit and save projects using the unlayer editor. Most of the work is already done using the script on GitHub, just need the js action buttons at the top of the page.
