wrt 1) one thing that's missing is if you look at the Process Modeler widget I believe it's not just a list of the added items, but also allows one to edit existing ones. Wdyt?

2) Ok, so both 2 and 3 are structured (or hierarchical?), it wasn't clear from you initial mockups - thanks for clarifying.

3) Michael Anstis, Guilherme Carreiro as I mentioned in my comments, I only starting working on this last night so didn't have time to work on this variant. But if you're good with this forms based approach I'll work on that next.
