and placing 2 workbenches 1 for each weaver so they can both work on there own thing?
Itโs allready what iโm doing ^^ iโm just talking about the queue 
When you have the two workbench, the two weaver and you craft 20 spool of thread, you have to craft 10 and 10 ! if you craft 20, only one weaver will work even if the queue is empty after the 20 spool :o
so the quee is the same regardless off the amount of workbenches? usally i donโt have more then 1 for each profession so not really experience with it
Yep, it look like it is !
The only way to make your two weaver craft is to split the amounf of item you want to craft !
Like i said, itโs not that bad, i mean, itโs just me who is too lazy 
But maybe some people think like me 
I think itโs possible to add to the game. Although the code should take into account crafter levels - if you have 1 pro-weaver and 1 apprentice, there can be a situation when a queue has a pack of items only the pro can make.
Ideally it should be toggle-able (in case you want to level your apprentice and keep a pro for difficult work only).
