Sweet Nightmares

This plugin is a simple plugin which allows you to sleep in beds in the nether/end without them exploding.

There are a few settings you can customise:
disableExplosion - Only disable the beds from exploding, they still won't work.

allowsleeping - Specify in which dimensions beds can be used. (the overworld can be disabled)

timeskip - Specify in which dimensions what percentage of players needs to be asleep for the time to progress, if at 100 this effect is ignored, if at 0 only 1 player needs to be asleep for time to skip to morning.

Aditionally there is the way Minecraft determines if you can sleep at the current time of day, this differs from dimension to dimension. If you are in a bed outside the allowed times you'll be instantly kicked from the bed.
In the overworld you may sleep during the night, in the nether you can sleep at any time and in the end you can't sleep at all, no matter the time.
