Remove item if exceeding maximum queue length

This module does not respect the maximum queue size.
It is possible to check the "Act as queue" option (from entityqueue module). This will cap the queue to the maximum length, but will always shift off items from the top of the list. When auto_entityqueue is setup to add new items to the front of the list, this item will be added and deleted directly, thus effectively doing nothing. This is not the expected behavior. I expect the last item of the list to be removed when another item is (automatically) added in front of the list.
