Thanks, this looks very handy, I will definitely use it.

Not sure I understand the question: we pop up an additional window
when there are more than one candidate even without this option, so
why do you say "+1 window"?  Maybe you had some recipe in mind that I
didn't try?

Not necessarily.  Perhaps xref-auto-jump-to-first-definition should be
tri-state, to allow users to request the same with
xref-find-references as well?
