I think we all agree that while we know a lot about the game we always forgot about little things about the uniqueness of the civs. I have seen multiple pros checking tech trees all the time to check if they have access to a particular unit or tech.
Also, sometimes it’s very hard to find certain buildings in the tech tree while it is in front of you all the time.
So, I am suggesting adding another drop down menu as shown in the below image. Selecting any building from that drop down will quickly take you to that building in the tech tree while highlighting it in the tech tree (like yellow in the below picture).
I am no UI expert so it is totally on them (devs) how the UI looks but this “Quick Link” feature to buildings can ease a lot of trouble looking for certain buildings while keeping everything else the same.
Note: This does not take anything away from how we used to use the tech tree. It is just adding another feature.
Below are the list of buildings that can be added as “Quick Links”:
