I know this has been mentioned, but wanna make sure it gets noticed. When the Stabilizers (they should be blue as mentioned by river song) are activated, while in flightmode or teleporting the interior does what it already does it only shakes when you bump into something or materialize, but when the Stabilizers are not activated then the whole interior shakes violently while teleporting or in the vortex. While in physical flight it will only shake violently every now and again, cause of "Turbulence" but instead of constantly shaking it swings about leans with the direction the TARDIS is moving.
