I have a 6 min queue but of the end of the time there is ~ 10 sec work left.
I don't really understand what you mean there.
Given your name, german would also work if your english is not the best. :D
About QOL, I will look into that right now.
Edit: QOL research is taken into account, though that only updates if you add/remove something to the queue, the mod will then re-calculate the crafting time
