IMPROVE MASTER PROPERTIES (GENERAL NON DESTRUCTIVE WORKFLOW)
After Effects has great options for realizing a non destructive workflow, but when you have many layers, it is difficult for you to maintain a certain order. The new master properties are great for resolving that and for having a even more non destructive workflow.
On the other hand master properties should improve a lot if they want to be as useful as node based workflow.
ADOBE, you could use both layer based and node based workflows. Cinema 4D has this kind of combination. I think the best workflow is use the bests of both two worlds....
Or maybe not, ADOBE, maybe you are developing a new and revolutionary workflow by yourself...;)
