Dip bottles and/or buckets into water/cauldrons to fill/empty them.

To differentiate in-code between filling and emptying for cauldrons, filling should take place when the item is pointing up in any capacity (the 180-degree span of pointing up) while filling should only be done when pointing the item down in some regard (though not the full 180-degree span).

Should be implemented as a server-side tracker, as filling should be do-able from above the block, and it just makes more sense to handle it all server-side imo.

Would also be neat if you could place water by turning ur bucket all the way upside down, and with both hands if there are too many false positives.
