MODoor 4.1 by Flyby

The MO Door v.4 as you might suppose is the successor of the MO Door v.3

The Basic features of the of Mo Door v.3 have remained the same in the MO Door 4, so users of the former version will feel quite famliar with the new one.

For those who are new to the MO Door here is a short description what it basically does :
The MO Door (Multi-Owners-Door) allows you to build a list of Sims separately for each door in your game. Sims who are on this list (the 'Owners-List' ) are able to use/pass that door.
Sims who are not on the list will be unable to pass the door. The list can be edited in the 'Key-Picker' (see screenshots: Basic Functions).
