There is currently no way in core to allow editing a term machine name via the admin UI. In Drupal, Taxonomy Machine Name module solves this problem:

Is this something that 80% could use, or does this belong in contrib?
That module claims integration with Views/Token/Pathauto, all of which are in Backdrop core. So does it make sense to have such a feature in core?

Hi Ernst, there seem to be a lot of modules involved, so it's not clear which one causes the trouble. I don't think, it's core. But I also don't think it's Leaflet. I verified with...
Disappearing administration bar. Is this a Leaflet or a Backdrop bug?
Do any of these issues help to identify the problem?
