I would love if you could add a redstone emitting ladder, which would emit a redstone signal if a player(or mob) is using/climbing it.
This would be a great companion to the jaded ladder, allowing the jaded ladder to open automatically when a player gets in range(ie: place the redstone ladder under the jaded ladder) like the functionality of a pressure plate in front of a door.
Another great addition would be an Iron Jaded Ladder, which would function similar to that of an iron door, and would only open upon a redstone signal(such as the one emitted by the Redstone Ladder)

Edit: Yet another good addition would be to add a configurable delay on the redstone ladder, so that the player would have time to get through the Jaded Ladder/Trap Door. (ie: the ladder would emit redstone for X seconds/ticks which could be configured in a small GUI)
