When I use 'Create Implementation' on a class in a namespace the namespace is automatically added to the front of the method. This is unnecessary if the namespace has a 'using' statement and I have to remove it by hand each time. This is a very small inconvenience but it would be nice if the 'using' statement was checked before adding the namespace.
It is good to know how much interest there is in a given feature request, I have put a note on the case about this. We are hoping to look at this sooner rather than later, but unfortunately I don't currently have an estimate for when we will do this.
