When I get a new blueprint, I regularly find myself reading the blueprints, then going to the book to see what I can currently produce, then reading the blueprints again. It never fails that I don’t pick the best buildings because it’s hard to keep track of everything. Some kind of marker in the blueprint you are going to get would be awesome. Like a little check mark if you can already produce what the new blueprint makes. It could even be different colors. A Green check if you can already make it and more efficiently. A red check if you can make it but not as efficient as the new blueprint. This would be an awesome quality of life change but wouldn’t take away from the strategy of the game, it would allow you to focus even better on strategy instead of memorizing endlessly.
