1. You would like the build queue from the master factory to appear as faded or shadowed in the slave factories.
If you have many slave factories assisting, then each will be feed from the master factory build queue and will build the next item in the queue when they are ready. The slave factories build queue will always be changing because the next item in the queue may go to another slave factory that has more build power, for instance. It makes more sense to keep the build queue only shown in the master factory, because it is only there you will truly know which unit will be assigned to built next.
yes and no , if main fac is on loop there would be no problem, tested it
I think it work like this : main fac has has queue --- main fac send request to build 4th unit(example) into slave fac --- shadow queue is appear in slave fac. and start building --- same again
dont see problem at all
----------------
1) main fac. has queue 3x mantis,2x medusa, 3x mantis on loop
2)main fac start build 2nd mantis(example)
3)slave fac. is made
4)queue is copied from main to slave as shadow queue
5)slave fac start build 1st mantis and then another
6)main fac. is building 3rd mantis, slave 2nd mantis
7)main fac. queue is changed to 10x medusa
8)in slave's queue remain not completed manta(building is continue), rest of old shadow build order is deleted and new build order is added in(10x medusa)
9)slave fac will finish not completed mantis and then start build 10x medusa
