What is the fastest way to implement a new objective function?
What about the continuous adjoint in this case? How to update it accordingly?

The derivation of the continuous adjoint equations and suitable boundary conditions (and resulting surface sensitivity) depends on the particular objective function chosen (and not all are mathematically possible). This is a very interesting research topic for us, as it requires some mathematical development for obtaining new continuous adjoint formulations. We are always interested in new objective functions. For example, we're working on temperature-based functionals and off-body functionals for minimizing sonic boom noise.
So, unfortunately, there is no short answer to your question, but you can check out the following subroutine in solver_adjoint_mean.cpp if you want to see how some of the current objective functions are included: void CAdjEulerSolver::SetForceProj_Vector(CGeometry *geometry, CSolver **solver_container, CConfig *config).
Perhaps we can discuss this more in the future (possibly in person). Cheers,
