There has to be a better way to manage production than what's available now. Could manufacturing use some kind of queue? At the very least, when a task is finished, the engineers could automatically shift to the next unstaffed project. Switching them manually after each project completion is tedious, especially when new weapon techs are unlocked and you want to do something like build 1x pistol, 1x shotgun, 1x rifle, 1x sniper, etc.
