Nice post, just as a disclaimer idle engies, or more accurately the linked version of the mod (and also some other versions) can cause MASSIVE fps problems in late game scenarios, especially when there are a lot of engies on the field.
Don’t get me wrong it is still a great mod and I personally use a very similar version myself, but it can really mess up your late game fps to the point where it can get pretty unplayable.
I played around with newer versions of the mod (idleEngineersReloaded for instance) and they don’t have this problem to nearly the same extent. Sadly, they also don’t have nearly as many signs over the engies and therefore also less functionality in my opinion. It would be cool if it were possible to include a simple on and off switch for the mod like with selection deprioritizer, because then you could simply turn it off once it starts lagging your game.
