There's a feature that would be useful to have. Show "lamp hint" in 
the line where c++ method is declared within a class with inscription 
"implement method" (if it is not implemented yet). When user selects it 
NetBeans should insert a stub like

returnType className::methodName(Arg1Type arg1, Arg2Type arg2[, ...]) {
}

taking into consideration special words like "virtual", "static", "const". The 
place where to put this stub should be selected by some rules. I propose the 
following:

if there is any other method in the class and method "className::methodName" 
is declared after "className::anyOtherMethod" its implementation should be 
after its implementation. 

class A{
void B();
void C();
void D();
};

------- somewhere in the project (in the same file or any other): -------

void A::B(){
}

//insert implementation stub of A::C ---> here

void A::D(){
}


If "className::anyOtherMethod" is not implemented yet we consider the method 
before "className::anyOtherMethod" and so on. If it the first method 
implemented in the class consider method below. If there is no method that 
implemented than: if the class declared in file.h user file.cpp for 
implementation, if the class declared in file.cpp, insert an implementation 
after the class declaration.
