Incidentally, I have not been able to find where the default sort order is applied? @bensheldon, feel free to move elsewhere if it makes more sense.

Hold on! This is insufficient. I hadn't tried with multiple pages.

All right, I have a solution! I had to pass state to the display_all scope. BatchRecord redefined the display_all scope so I had to introduce an unused parameter to respect the contract.

End of page 1:

Start of page 2:

Notice that job 01d... is present on both pages. Not sure if that is acceptable.

I added ordering for all of the states. The overall principle I went with was: most recent relevant change first. e.g

• All: most recently created
• Scheduled / Retried: next scheduled job
• Queued: most recent job to become queued
• Running: most recent job to start running
• Succeeded / Discarded: most recent job to finish

I think for Queued and Running, there is an alternatively important question that's relevant which is: what is the oldest or longest running job? I will defer that until someone wants to add a feature to "reorder".
