It would be great if there was an option to navigate easily from an overriding method in a child class to the respective overridden method in a parent class. (It should jump to the closest parent which declares this method.)
Simple example:
abstract class Gradpa {
    virtual void foo() = 0;
    virtual void bar() {
        // ...
    }
};
class Parent : public Gradpa {
    virtual void foo() override {
        // Navigate from here to the Gradpa::foo()
    }
};
class Child : public Parent {
    virtual void foo() override {
        // Navigate from here to the Parent::foo()
    }
    virtual void bar() override {
        // Navigate from here to the Grandpa::bar()
    }
};
