Hey Ferris,
As you know the inter-sector boundaries and the related route structure is not exactly conducive to auto-handoff, that is too many crossing routes to muddy the water of where is a god place to hand-off. So no auto-handoff, so 2 mouseclicks per handoff.
We can't man the single man per position roster so no chance of dual manning anytime in the next decade here. Therefore as a guy on your own controlling when an aircraft calls you relating to sector loading and frequency congestion is important.
Thanks.
