could you tweak vanilla cauldrons somehow so that they are more useful? i mean, even if you could just make them combine when they are next to each other like tables or chests, you could use them as bath tubs for decorations sake.
EDIT: i mean, you seem to be pretty good at that, finding the most useless bits in minecraft and making them awesome, and i really can't think of something more useless than vanilla cauldrons.
Well, they are fairly useless, although you do need them for potions. It is a little odd having two different cauldrons. Perhaps they could be combined somehow.
