Feature Request: Reorder array items between arrays of the same shape

[damnsamn]

It would be great to be able to reorder (or otherwise duplicate) array children between parents.

Consider a nested array setup, where each L1 array item expects an array of L2 items:

• L1A
  • L2A
  • L2B
  • L2C
• L1B
  • L2D

There's currently no way to shift, for example, L2C into the L1B list. The only current way of doing this seems to be creating a new item under L1B, copying across all the data from L2C, and then deleting L2C.

As a real world use case, consider a navigation submenu that is split into columns like this:

In this case I've made an error: I accidentally put "Brand Design" under "Industries", when really it belongs under "Services". A user might intuitively attempt to drag Brand Design from one array to the other, which would fail. They would have to go through the same Create New Item > Copy/Paste Data > Delete Old Item as described above.

I Imagine there'd need to be some sort of immediate validation in place to ensure that the shapes of both arrays are identical in terms of schema.

I would love to see this as well. Any chance that this will ever get to the roadmap?
