Another tiny mod. Boidster was playing around and it worked; maybe it’ll be useful to someone.
Right-click with murky water jar onto water or any terrain block to “empty” the jars. Will not add water into the terrain or re-fill “holes” in water. Just empties the jars.
The forum topic of the mod is here.

Doesn’t seem to be working on solid blocks for me – does work when right clicking on water blocks.
