Tech tree database

Hi, I've been playing the game for a good while now and I always thought it would be really cool if the tech tree had a function where you could click on the picture and it would tell you a little bit about that technology, such as when approximately this was invented in history, who by and why it was a benefit during that time. Or even just a sentence explaining what that technology was. I enjoy the game because of its attention to detail and it's close ties to our own history so it would be cool to learn a little bit about those things as well. I'm always googling various technologies from the tech tree anyway to learn more about them. Ie muskets or plantations etc. so I think that would be a great addition.
