I had to do some measurements to make sure the geometry back there was alright and that there was plenty of space. That door is meant to go to the CO and XO's quarters anyway, and some backup escape pod access, though that could vary depending on ship.
Who finally moved this? Need to know which NTSE mod approved this so that I can fill out the appropriate part of the wiki properly.
Edit: Okay, I see Cadet did it now.
To explain the reasoning behind the Captain's Chair being where it is, those doors behind it are more meant to go to some extra escape pod access, and the CO/XO/MEGAMI rooms on the Plumeria. On smaller ships, they go to the CO's suite or MEGAMI in most cases. They're not meant for access by most people. Also, there's more room back there than the first image implies.
This was an effort by Yaichiro to allow everyone to look at every other station on the bridge unimpeded and also to allow the CO to feel like the bridge was even larger as they sat in the chair -- something Yaichiro wanted to do for Hanako. People can walk past the CO station two at a time just like they can walk through the doors two at a time, even when the door is in use. Because of that, it's not really a bottleneck.
