First, I'd like to thank you for the mod. It's by far my favorite linked chest mod due to the linked pipes that no other has so far on 2.0.

Now for my suggestion, I was hoping you would consider adding an option to restrict the shared inventory to a specific surface in Space Age? I would like to maybe play with this, but still use platforms to move stuff between planets to keep things different.

Usually, there is only one surface. If distinguishing surfaces, the display of shared areas is difficult to handle, and there are many surfaces in certain modes. In the space age, on other planets, there is no need for associated pipes, and fluid handling is relatively simple. You can try using pipes instead of associated pipes as much as possible. Finally, the MOD is very convenient, and it is also a pleasure to use the associated boxes and associated pipes with minimal effort.
