Regarding the Copper Golem

Hello there dear developers at Mojang! I wanted to share some ideas / needed fixes regarding the copper golem. I tried to create a kind of auto sorting system with the golems. There are 2 problems I've encountered: 1. The Golems aren't able to pass each other on a two blocks wide walkway, wich gets them stuck. It should be possible for them to pass each other, since they're really small and also only need a one block high room. 2. There should be a system which enables the golems to "see" or "remember" what's inside a chest. The golem searches all chests every time, even when he already stored an item successfully in a chest. He should be able to remember in which chest he put the cobblestone for example, instead of having to search all chests again. Greetings and best regards, Pierre
