Here's the current state of the interior quarter doors on the Myon (The Great Tree) Quarters map:
The problem with this is that this "non-door" cannot be opened. If you are inside, the only way to Open the door to let someone in who has knocked is to Enter the door, going outside. You then have to go back through the door, which requires you to wait for the full transition delay (and often you end up doing a in-and-out pingpong trying to get both you and your guest on the same side of the door). It makes no physical sense that we can't just open the door that clearly exists.
There are doors on the outside leading in; can we get those same physical doors on the inside with open/close functionality?
