The shared queue is really nice for /most/ purposes, but training new crafters and fishing for ‘fine’ products both have motivations for more control. If they kept the main queue, but /also/ gave crafters their own personal queues (that we could add to through some more convoluted mechanism), that’d be ideal imo.
At the moment, it seems like once an individual crafter starts a line item, it’s “reserved” for them (their face stays on it, even when not working on it, and others don’t seem to take it over, at least when I’ve experimented). So to skillup low level crafters, I create some production for the high level to grab, then add a large-quantity order afterward for the low-skill crafter to claim. That way, once the high level finishes their distraction, the lowbie will still have their order ‘claimed’, and will get to leave it and come back to it as needed. Means you have to mass-produce a single thing rather than diversify, but at least it takes (relatively) little micromanagement - just have to make sure the right people initially claim the orders, and trash them & do it over if they don’t.
Alternatively, the high level can be given one huge order to handle, and hope it keeps them busy while the low levels complete the rest, but if the high level can’t do that single big order for any reason (runs out of supplies, etc), they’ll chew through the lowbie’s stuff.
