Shared lists stay in step — drag an item and everyone sees the same order, on every device. List colors reach the others straight away too.
Easier reordering — press and hold an item, it lifts, you move it, and it settles back into place.
Sharing without typing — add an optional name so people see who you are, and pick from the people you already share with.
Also: simpler ready-made lists, smoother screen changes, and opening a list is instant again.
