could you make mod similar to this where the more a the activety of the building it will automatically be marked for an upgrade for a certain Quilty (depending on activity)

Thanks for the idea Spro!

Let me see if I understand, by marked for upgrade, you mean that bots (or the player) would need to handle the upgrade with an item from the logistic network? Basically you wouldn't get the upgrade for free (like in this mod)?

Regarding activity level, there are a few ways to track it. Would you want to see that as total items made, or by how many hours they've been churning away (regardless of items)?

correct and for activity level it might be hard to track but the more its doing stuff (not being idle) and add maybe like a 2-3 hour delay so it has time to do stuff when you first switch it on

Right on! Thanks for the idea, this would be helpful and definitely the kind of automation I'd want too. It's a fun but hard challenge. I may take this on at some point. I'll update the thread if I do make something.
