Version: 1.0.67-gtnh

Currently dual interface in blocking mode would check for blocking individually per side. This generates a lot of problems for automation setups: Duals would ignore blocking to deliver pure fluid crafting orders if nearby chest is empty as It checks for blocking on chest, sees its empty, then fails to push fluid into chest and outputs it to any other side. Same for reverse with empty tank and only items crafting task.

This also prevents setups which require blocking if either tank contains fluid or inventory contains items as pretty much anything but ae2fc buffers can't move/accept fluids and items from same face of interface. Major pain when trying to automate complex multi blocks.

Suggestion: Add a new toggle state to blocking button in interface gui to make it do a shared blocking check for all faces. So it would block any recipe from being outputted if any one side has any item/fluid.

I understand this change request may not attract enough attention and thus not be implemented.
I believe this feature would make the mod better.
