It know the code in java and I think easy migrate to QGIS.

<div><div><br clear="none"><div><div dir="ltr">Ok I guess you can see where I am going to go with this email :-) Is there any point to allowing users to simplify point layers? Alvaro, can your remove the point rendering tab in layer properties (and I guess check internally that you are not trying to simplify point layers)? Or is there a use case for point simplification that I am not getting?<div>
