It would be nice to be able to set a preference to a certain WU which has
an earlier due date than the WU's that are currently being crunched,
instead of the first-in-first-out / first-come first-serve policy that is
implemented now. Maybe as an option in the preferences tab.

If such an option were controllable by the end-users, it would mess with BOINC's internal scheduler.

Remember that BOINC has to schedule for workunits with a deadline of a few days to a year. If BOINC ran in deadline-mode only, workunits with a deadline of a year out wouldn't get any processing time until too close to the deadline and could run into issues meeting the deadline.

It is honestly best to leave it as FIFO (first in, first out). BOINC will automatically detect if there's deadline trouble and switch to EDF (earliest deadline first) if need be, but will default to FIFO.
