AnimStack is a collection of tools to simplify creating animations in GIMP. It makes heavy use of Layer Groups, introduced in GIMP 2.8.
A simple example of a problem this script might solve: you have an animation, but you want to put some text on top of it. Normally you would have to add text to every frame manually, but with AnimStack this task is completely automated. AnimStack is perfect for post-processing your GIF animations and adding various simple effects to them.
