I have created a picture which I would like to save. However, I can't see any 'save' option or an icon which would suggest that it has been saved automatically. When I press 'Download', it gives me "Download We're working on your file. You'll be able to download it soon." message. When I try to leave the design, it gives me a message that my work might not be saved. It would be useful to add a 'save button' so users know at which point their work has been saved.
