Awesome thanks - I ran into the same issues with the images... no drag/drop, no copy/paste. That is a big one to get implemented since we have been spoiled with those abilities on Steemit. 

The Save/Load did work for me. I closed the browser, went back and clicked load to make sure and it pulled it back up. Let me know if you still have that issue.

Also, if you have an account on Medium, you can test posting to that as well with the test url https://test.masdacs.io
