The big switch from legacy layers to nodes

Preview Give feedback

1. This all had to happen at once because it fundamentally breaks major functionality. The first half was done through a continuously-rebased branch living atop master. The second half was done in master in between production releases while many features were missing and caused crashes until each were fixed. Tracked in:
