I suppose you cam here expecting a bigger post but for the moment this is just a placeholder. I can tell you that I've had play with the new bulk editor and the ability to tinker with metafields is going to be super useful. For ShopifyFD fans, this new update will compliment that tool really well. It might not seem that special but when you can start doing things things like this (pic below) suddenly product edits are going to fast.
I'll update this post once I've cleared some time for a ramble.
