Auto/manual save within editing mode or narrow mode

[dalbandea]

Currently autosave only seems to occur when exiting edit mode and all narrow modes, which I find a bit inconvenient: if I want to save and keep editing, I must exit edit mode, narrow mode, and then look again for the section I was editing to get into narrow mode and edit mode again. Also, many times I want to switch apps while editing within a narrow mode and there's the risk that the app gets closed and changes are lost.

I think it would be better if autosave is triggered every time one exits from edit mode. Maybe it would also be convenient to have a manual save option within edit mode?
