Our users are very impressed with this plugin and it's ability to quickly visualize our mess of upstream and downstream jobs. In our pipelines, we often call the same job several times - different parameters - so it appears multiple times in the diagram. Not a bad thing; they're all nicely sorted alphabetically. But for our use case, if they were sorted chronologically, that would better help finding the specific job.
I don't know which would be easier to implement - a global setting or a setting on the display page itself, where a user could toggle back and forth.
