The dilemma here is:
* Undo schema and CLI to simplify UI
Pros: less work in UI
Cons: reduces functionality and undoes what is already done (affects
help and CLI)
* Implement UI to handle nesting and do not touch schema and CLI
Pros: Does not undo anything and does not reduce functionality that
someone might want at some point
Con: Much more work in UI
* Leave CLI and schema as is but in UI not support nesting
Pros: Medium amount of work
Cons: Ugly

I do not know what is the best approach here.
IMO first option is less risky and less work.
