Long work table priorities

[Ackapus]

I love the fact that now we can finally do something with art skills, and that the tailor table can make more than shirts, pants, and cowboy hats, but what I'm finding is unfinished works piling up in my stockpiles.  Because of the extended nature of those productions, you can't tell a colonist to work them, and you can't tell a colonist- even the author- to do anything useful with an unfinished work.  I don't like wasting resources any more than the next guy, but I can't tell if this is a bug or simply colonists being dumb.  (I love their fire-evading tactic during mechanoid attacks of running away from a fire directly into a cluster of centipedes with inferno cannons and autoguns.  Real smart, guys.) 
What I would propose is an extra flag to any production table whose works can be left unfinished and carried away from the table- that the table would prioritize the completion of ANY applicable unfinished works in the resource search radius before allowing a new one. 
And maybe a clarification as to the conditions one needs to fulfill before you can start working gold or uranium into art or weapons?  I've stockpiled quite a bit of both those resources, but I have yet to see anyone try to work them, even though I've got people with 12 to 14 in crafting and art skills.

Try downloading the game again, A8c fixed this: "The binding between workers and bills will no longer time out. This should eliminate problems with workers starting the same bill several times and ending up with multiple unfinished versions of the same item."

You need 20 times as many gold, silver, or uranium to make something than the number that's there for regular materials like wood and steel. So, 2000 to make a sculpture, for example.
