Yeah originally I was thinking it would be nice to use an animation multiple times within the same project, then you'd avoid most the pitfalls of resources being unavailable.
I hadn't thought initially about exporting animations from the project and allowing for them to be imported/edited/used in other projects or shared/collaborated on until this dialog started.
As its developed further, the concept of making animations available cross-project is really compelling. I can just see a vibrant marketplace or user community openly exchanging animations. Pretty cool stuff!
I'm Looking forward to seeing what you come up with if its a feature that can make it onto the roadmap! :)
