References dialog (restricted)

A sandbox branch cloned from References dialog for some experimental modifications.

I want to use most of the functionality of that (it allows inline creation and editing of nodes referred to by entity reference) But I want to remove the re-use and autocomplete function.

In my use case, a parent node may have a number of subsidiary nodes, but only that parent ever refers to those targets.

Making a user profile form - where users can add a number of "positions" - Work experience type stuff.
Each entry is a complex data type, with extra fields (dates), tags, so, each 'position' is a mini node, and the users can make a few of them.
User can change the order if items, add, edit and delete them.

BUT they cannot re-use them. Autocomplete is not helpful. But the rest of the architecture that references dialog provides IS.

This is a branch to see if I can work my requirements into this module.
