I'd like to have some sort of autosave or recovery option for Fusion scenarios so that if you are working on a scenario and a browser issue occurs, you don't lose all of your work when you refresh the page.
Either an autosave feature, or some kind recovery mechanism similar to the way MS Office or Linux does where it hangs onto the temp file you are working from and offers to load that temp file for you on the next time you try to load it.
