[Cin] automatic save of

Mon Jan 18 11:43:36 CET 2021

Thank you very much Reuss András, with the multiple backup copies you have
done an excellent job, perhaps you could limit these so that you do not end
up with thousands of copies, with about 50 would be enough.

New users should be told how they can get their work back in the event of a
sudden shutdown.

What Kdenlive does after a sudden shutdown is on the next startup open a
warning to restore the last automatic save. This is usually very common in
these types of applications and is the easiest for the user, since the
normal thing after a sudden closure is to reopen the application.

I know that this is done with a file that checks the correct start and
closes of the application, when it closes correctly the value that is
written in this file is 0 (False), otherwise it remains at 1 (True) and
when starting the application again and being at 1, it launches a window
that allows loading the last backup.

I know this because that's how a programmer explained it to me, I think I
would need many years of programming study to be able to do something like
that.
