DON'T MIND ME EXPANDING ON THIS IDEA
the room itself is a small area with your blockhead, who spawns in the middle, with 4 doors (+ 2 side 'doors', which are simply you going off to either side of the screen to roll onto the settings/server options)
this major 4 door area (join, start on one side grouped together, tutorial on the other side alone, and a new selection called 'edit' smack dab in the middle)
going into the Edit door will let you modify the join server, start server, and 'hub' doors by simply building the sets. but, not the options/apply rooms
if you find yourself doing something stupid like blocking the edit button, you can press escape and simply revert to the default hub for a bit
the join server/start server rooms are technically just little pedestals with monitors in the middle of the room. standing infront of the monitor cues a short-ass cutscene in which your character walks to the very center of the pedestal and zooms into the monitor while the screen blacks out, when the associated GUI appears
transferring to either of the sides of the hub, going through any door, etc, simply fades out the screen and then fades it back in
