Totally agree with and support your call for auto save.
I have already developed the habit of clicking the blue save icon following EVERY step of the process. If I reposition, I click - If I add, I click - if I ANYTHING, I click. This is now automatic for me as I work with my graphics programmes a great deal and over the years have all but shed tears at some of the work I have lost AND, it is never the same the second time 'round (for me).
Great suggestion for the further improvement of this great Scrapbooking programme.
Kind regards and thanks for the kick-start on petitioning for auto save.
