Thanks a bunch, Rabbit
This also happened last time I was making a similar request - I think it was Vector3 subtract or something.
It's very kind of you, and I can import it - but next time I start a new project it's no longer there. And next time someone need it, they will have to find it in here.
point being: I think these standard math-thingeys should be part of the basic package.
But thanks again, it was very nice of you
