like what we can do with the belt checker but then for fluid



In general, anything that helps understand fluid-flow will be a good thing.
I would love to be able to read the color from my pipes.

This needs prioritising… for too long fluids have been a pain in the ∗∗∗∗ when logic is involved.
I am sad that the fluid reader/sensor has not been added in the 1.0 - needing to hard code fluid colours in a MAM is a silly restriction, when we can read belts.
Fluid readers would be extremely preferable.

Heck yeah!
