The fix that I proposed to complete is not exactly a bug. It is acutely an accommodation and facilitation to the user of thimble.
After I fix a but on the saving pattern when the user was logged in. Professor David Humphrey asked me to go further and now display something now whenever the user is not logged in and make changes to the code and those get saved locally by brackets to the browser.
I also invited Luke Pacholski to give some hints and his opinion as a designer to how it should be done.
The biggest challenge is to handle the references between Brackets and Thimble, but Professor Davide showed me how to find in the README.txt other methods that are using a similar reference that I might have to use.
