Change the number of bones in Limit Weights, in 2.7+ I'm trying to limit the number of bone-weights per vertex to 2 or 3, and there is an operator in Blender in the weight-paint mode (Tool pane) called "Limit Total". But there is no way to change the default number of 4 weights per vertex in the UI... that I can find at least. Is this a bug or omission in 2.7 or am I just UI-blind?

How to restrict vertex weights to no more than N number of Bones?

I can do it through the python console as the underlying operator has the arg "Limit=4" as default and can be changed, but it is somewhat inconvenient..
It is in the UI (you need UI glasses ) in the operator properties panel:
