I suppose it would be easy to implement, to make the creation date of an object change to the current date, when an album or a custom object is turned into a peak or a range (only in this direction, not the opposite).
Why ? Because many of us start a draft of a mountain, it takes few days, and when we sumbit it, it doesn't appear in what's new unless we do it again from scratch. Same with albums, I started many peaks or areas just by gathering photos and realizing later that there is material for a more detailled page.
Thanks for considering this improvement
