I work with files every day, and I'm not sure I would have realised I'd needed to save manually with the original MapHub UI either. A web-based interface that looks like that, I expect it to be transparent. If it'd had three icons (the classic blank page, open folder and floppy disk) in the top left, then I'd assume it would need manual saving. (I'm not saying that's what you need to do, just analysing my own intuitions)
