Expand FRBR group of records within the search results
I suggest the ability to expand a FRBR group of records within the search results, rather than the "view multiple versions" link showing a new page of records, from which you have to go back to the original results, isn't a good user experience. This would work nicely with infinite scrolling in the new Primo UI.
It should be possible to set a threshold for the number of records in a FRBR group this should happen for, e.g. six because most of our FRBR groups are for up to six editions of a title, whereas others are for tens of records in a series (Advances in..., etc.) which you still want displayed as a new set of results.
