I'd just like to note that in certain applications (like SLY/SLIME where
this request
hails from), sometimes xrefs are grouped not by file, but by type (a
symbols's
references includes "who sets", "who calls", "who reads", and so on) . So
if possible, and in general, this type of solution should be thought as
"prepend/append group name".  There can even be multiple grouping
strategies.

But one can also think about: select group first, then item within group.

Just my two cents.
