It is called PlusMinus.
PlusMinus is a compact number slider that lets you switch between positive and negative output directly on the Grasshopper canvas.
The idea came from a small frustration I had while working with long Grasshopper definitions.
I kept setting a number slider, then adding a Negative component whenever I needed to reverse the value.
It worked, but repeated across long definitions, it added clutter and another place for mistakes.
So I wanted a slider with its own positive / negative switch.
Now with PlusMinus:
-Positive mode stays gray.
-Negative mode turns red.
-The value stays easy to edit.
-The output sign changes with one click.
-It is also now published on Food4Rhino.

I would love to hear your honest feedback after you test it in a real environment.
Would this be useful in your own Grasshopper workflow?
