Taking waters from lakes and placing it to your wells? or more interactivity with liquids like making soup with water. Well a bucket or for more advance is like a vacuum or the matter manipulator
Pretty sure that's on the to-do list, no need to ask for it. The point of the suggestion forum is to ask for something the devs wouldn't normally think of when making the game, like an imbalance they overlooked, or a feature that would boost the game's appeal beyond adding hats like they were trying to emulate TF2 or something.
