Too bad, it just gets on my nerves.
@kingkeith: thanks for the feedback
Even when the Session.sublime_session is edited and fixed, ST3 seems to use it at start up, then overrides the settings with its own.
I can't help thinking it is a bug, not a deliberate feature. Maybe Find History can be thrown, the overriding user preferences looks like a bug. Is there a bug tracker ?
@frou: it can be useful on some occasion, but I'd really like to be disable by default in my environment.
