Fluid interaction key that lets fluids behave like regular blocks.

There could be a fluid interaction key (editable in settings, with toggle/hold options in accessibility; default: hold). When held in Creative mode, fluids behave like regular blocks: left-click deletes/breaks the fluid, and right-click places a block on top of it. A thin outline appears when hovering over a fluid, including flowing blocks, to indicate interactability.

This is especially useful for builds like waterfalls. If a block is accidentally placed in the pit at the bottom, water may spill out even after rebuilding the pit. With this feature, players could delete the flowing water directly and restore the intended flow.
