Responsive breadcrumb in SUI resource tree view
Description
As a processing archivist, sometimes I'm adding items into extremely long existing series. It can be really confusing about where I am in the resource when I'm in the middle of some indented series. It would help a lot if the breadcrumbs at the top could be responsive to whatever series/subseries I'm in, as mocked up here. Would it add a lot of processing time to accomplish this?
