JSON Enhancements (Better Loops, Ordered Loops, Better Path Expression etc)

EDIT : I released a Construct Tool allowing to do this and much much more :

JSON+ overboy.itch.io/construct-3-json-plus

I can agree with #1 and to some extend with #2, but #3 is definitely unrealistic and will not be compatible with the current expression structure.

I would suggest posting 3 different ideas, to allow people voting for each idea separately. Ashley has repeatedly asked not to put multiple suggestions in a single post.

Yeah I agree it's better to seperate suggestion in most cases if they are really different but I also feel like #1 and #2 are somewhat related.
