I would indeed love this idea! just make it that the second tap on the title of the list reverses the order. Tho the dwellers lists on my Iphone 5s make it crash is i have been playing for a while before opening it.
Reverse sort order is great, there should be a persistent scroll bar on the right too. Scrolling is a pain in the butt.
Holy god yes! Especially to find low happiness people.
And to 1-up the suggestion, selectable sorting. e.g. all people with strength between 3 and 8?
I too would like to switch between ascending and descending order.
Yes, please! I would love this and would make much use of it.
