Possibly add a configurable timer to close SecretDoors automatically.
Known issues:
Permission node secretdoors.use will NOT prevent players from opening SecretDoors via Redstone power. To truly protect doors from being opened you will need to disable Redstone use in the config file.
Redstone torches placed on the doors bug out because they provide power to the door - They have been blacklisted as a result. If people REALLY want Redstone torches place-able on SecretDoors let me know and I'll look into a workaround.
Doors with a torch on them cannot be opened while the player is also holding a torch.
Double doors are a little screwy if you use a mod that opens both doors when you open one.
Please let me know about any other bugs you find.
Changelog:
1.4.2 - Compiled with SpigotMC for 1.8
