Hey just noticed I cant really pick up the water i placed with the Bater Wucket, so I think this could make for a cool feature if possible.

To explain the title further:
Make Bater Wuckets act like empty buckets when right clicking the air (or something similar to that) so you can also pick up that water.

I agree that this is rather useful, in fact it's been on my list for a long time. I've now implemented it in the form of the separate Bempty Ucket (which acts like an infinite empty bucket for any fluid) in 0.3.4 for 1.20.3+

Cheers

+1, this would be really useful
