Hi JTB, I definitely want to make improvements to the history mechanism, I have some ideas on doing that for v2. It is a tough area of work though so it is going to be a while into v2 before I'll be able to focus on it, I am planning on focusing on the object organization tools first before that.

Re: #2 - instances / references - I would definitely like to add a kind of "block" instancing mechanism in the future but I'm not quite sure when it will happen.

The focus of that mechanism would be to have clones of a base object that could be automatically updated when the base object is changed.

I'm not so sure about the idea of editing the clone instance and having it propagate back to the original, that kind of seems like an unusual arrangement to me, probably at first that would not be a focus but instead be more focused on Base to Clone updating instead of Clone to Base editing... But we'll see - it will be a while before I will be able to focus on that.
