TL;DR:
If a blueprint book only contains deconstruction or upgrade plans, it should change the color of the book to red/green respectively.WHY:
First of all, it would look cool. It also shouldn't be very much work at all.But more importantly, visual clarity!
Can you spot which is my deconstruction blueprint book? I know where it is, but my eyes always get caught on other deconstruction plans or even other more red items. My deconstruction book is arguably among the least red items in the second toolbars. (exaggerated just for illustrative purposes)
