Order lists by 'date checked'.
So you can see in what order you saw the movies on that list.
This has been added. Expect it to be online soon!

This is an interesting idea, though part of me wants to be able to retrodate some checks.
I like this one too, and it should be easy to implement (they already offer that option under "all checked movies").
Yup, liking this one. One vote from me.
