it would be nice to be able to see what the oldest N jobs are before they are prioritized. I'm also a little unsure how to promote/explain the oldest jobs functionality so that it gets used appropriately. should we add a repeat command to the control panel that calls it once a ?

all of these are "maybe? dunno yet, need more experiences" to tell, i'm still experimenting with numbers to use here

a reporting tool might be a good idea, but i'm not sure how to go about that

i have a separate script that does something along these lines but it is very much not ready to be shared with the community
