Collapse jobs

Since jobs can often take a few minutes, I tend to queue up several variations, then go do something else for a bit. When I go to post them though I'll often accidentally repost an old image because I don't know where my current batch started.

It would be great to be able to visually collapse job runs, so that I can keep track of what's old and what isn't. My current solution for this is to remember the latest timestamp of the previous batch. Not exactly ideal :)
