This gives a little bit of control and even lets you do a little bit of each setting. It's not full controls but I'll keep adding more.

There are three sliders. FIFO, LIFO, and Random. That is:

• First in first out
• Last in first out
• Random

As far as individual controls go I would order the priority, to first be able to remove an item, then to reorder items, then to be able to edit items in place.

Those kinds of things will happen when they happen.

Also the post whenever queue page has been decluttered and it only shows your own items. But if you want to see the full queue you can find that at /wheneverqueue/all.
