I am a composite supervisor working mostly on animated TV shows.
our process means grading and effecting long strings of shots with sequence specific repeating effects and setups. We work with large and small teams of artists around the world.
We would absolutely love the ability to drag and drop an effect or a stack of effects from a layer to a shared library so it becomes automatically available to our artists around the wolrd.
This would be a big boost for speed and reliability of our collaborative process.
Right now it's "possible" through the classic system of saving an animation preset file then sharing that via mail or chat, then installing etc, or sending a zipped comp collect, but that's a lot of obsolete slow footwork. We could just slide animation presets to/from library straight off/from layers and comps. It would seem you already have the hardest bits of the backend already built in the adobe libraries system, it would just be a matter of figuring out a file type ?
Ideally this could contain layer properties, keyframes and plugins, the luxury version would be to include the ability to drag in a whole comp or precomp and include its dependencies
