While the load-balancing queue is very nice with a large render farm, for smaller farms it may be more useful to complete jobs one-at-a-time. Eg, it may be better for an upcoming draft submission to have a few shots fully rendered than many shots partially rendered.
It would be nice to have the option to process the queue one job at a time, in user-defined order a-la Backburner or other queue managers. This can sort-of be achieved by setting all jobs to HIGH priority, however once submitted I don’t think their position in the queue cannot be adjusted, and more granular prioritization and re-ordering would be very useful.
