Describe your feature request

It's quite common that you would want to enforce that every model a a unique weight. I've marked my weight column as unique, but new items are not assigned the next weight class, they just default to zero. I would be awesome if something like the above autofiled the weights (under the hood too, if hide_ordering_field = True) and would add it to the end.

A workaround for duplicate wights is to filter on an datetime column which is set by creation date
