# Layered Actions Prepwork

## Things to think about

Here I (Sybren) want to list functions / areas of Blender's code that will have to deal with the to-be-multi-layered nature of Actions.

These (I hope) may often boil down to "do we create a new layer for this, or do we update the top layer?"

- `BKE_animdata_copy_by_basepath()` and `BKE_animdata_move_by_basepath()`
