Request for a Save All facility
It would be very useful to have a "save all" facility as do Microsoft's and other's products: Pressing Ctrl+Shift+S saves all open documents in sequence.
It is very disconcerting to realise I have 7-8 documents open from a book at the same time and none of them has been saved, sometimes for days.
I have once or twice been caught out by Windows crashing with a large set of documents open and then found their contents in various confusing states.
It would be so much easier if I could watch the stars slowly disappear from my tabs/eyes by pressing a short key sequence.
