That's kind-of the problem, you need such a high level of knowledge to get involved in coding it limits person power.
I remember when I started making parts with no experience in anything EE and when there was no one around, so it was days and days of trying stuff and seeing what the outcome was. It gets to that stage where you get stuck for days because you don't know enough about it to think of a way around it.
I guess we have to take FZ for what it was intended, a simple EDA with a BB view. It's going to be fine for me because I'm never going to be a genius in EE, so won't need high-end stuff, but it would sure be nice to have the extras.
