First of all, we click on the trading interface of the AI, which is to buy things, so why are the purchase options for each resource shrinking? We have to reopen them every time. Why not give a global option to let it expand or shrink by default？

Secondly, there are always times when we need to buy a lot of AI resources, for example, I am short of food now, I will want to buy a lot of salt, or buy all the food-type luxury resources of that AI, why not give an option to buy all the "some type of resources" or "all this resources" of this AI at once？

Finally, why not separate the transaction route view, and instead choose to merge it on the interface that communicates with the AI? When looking at the trade route, the two 3D models on the left and right only obscured my view？

It's been such a game for so long, it's hard to believe that this kind of place hasn't been optimized

This one would surely be a welcome change. Finger crossed for the next update.
