To provide context for a given job in a folder structure, we have the path to a job shown as "f/f/f/job"
In version b23 of BlueOcean I noticed the behaviour of the compaction changes:
On the front screen for 4 or more levels you get:
On the job display
And then in the build display
(note that the underline decoration is shown even when I'm not hovering over it - which is different to other screens)
I also think that the vertical alignment is a little off, and the underline doesn't look good (in above image), but looks ok once expanded
