Quick demo of the new For Each Object (Ordered) condition in 0.95.
Like For Each, it allows you to iterate instances of objects one-by-one, but using an expression to determine the order. In this example, it's used to sort Z orders by Y co-ordinate, which you can notice by dragging the butterly sprites around.
The event used is:
+ For each Sprite ordered by Sprite.Y Ascending
-> Sprite: Bring to front
This means it iterates the sprites from top-to-bottom, bringing each one to front. Since the bottom ones are brought to the front last, they are on top.
