Ahh mhmmm, ok I see what you mean. Yes, this is a possibility, I agree.
I will use that but it sounds a little tricky to me (you could say to me : "Well, use
tags directly") : I keep some regrets that blueprints doesn't have an option to let user adding any fields.
For example, it could be cool to have a simplified option like
addfield: true inside the blueprints for each fields types : radio, checkboxes, text, textarea, etc...or maybe I'm off-topic.
Thanks you texnixe
