Can we add to the signals:
1) set union: something like the signal-U
2) set intersection: something like an upside-down signal-U

That way I can edit descriptions describing combinators more precisely .. just doing \/ or /\ for now

If this is about description text, that text box supports Unicode, correct? Assuming that Factorio's font(s?) support the symbols, you should just be able to enter "∩" and "∪" directly.

oh wow where was THAT in the tutorial
