Simply going into block config, and changing physical from true to false. I could probably make a mod for this, but it would be nice to see this puny detail implemented. Currently I only use water for "holo screens", but making water nonphysical wouldn't affect current decorative schemes, while opening up a whole new variety of uses such as weapon barriers, star dock door shields, jump gate decor, and much more.
I am very surprised that no one has thought of this before.
