I would like to request the ability to configure whether or not beds can be used within the dimension.

I am not referring to being able to sleep in the dimension, just being able set it in the config so that there is the option for being able to right click a bed to set spawn instead of it blowing up.

The dimension is just a datapack. You can change that behavior with your own datapack. This mod just adds the teleporter. The rest can be completely changed with datapacks.

I don't know how to make datapacks though. how would I make a datapack to do this?

There are plenty of resources for this on the internet.
