Doors
Each door has it's own set of properties that can be individually set (so no groups). These properties includes things like acceleration, max speed and how long it will stay open. So apart from these properties, the fast and slow brown doors are pretty much identical.
There's a property flag for doors that say "Area behind door not visible" (most doors have this) and "Area behind door visible" (used for Facility bathroom stalls and probably those others doors you mentioned like windowed ones).
