How to move the "All" tab to the right in Jenkins?
One option is to add a new view, remove the "All" view, create a new view, select  "All" and let it start with "z", e.g. "z-all" as the view is sorted alphabetically.

There is an open issue that indicates that the ordering of tabs in Jenkins is alphabetically sorted and cannot be changed at the moment, e.g. change the order manually.
