I will discuss how recent developments on quantum reference frames can be viewed as a quantum extension of classical relativity principles. This leads to a quantum frame dependence of the very notion of subsystems and thereby to a quantum relativity of correlations, superpositions and thermal properties. Time permitting, I will discuss how these observations extend to gauge theories and gravity where dynamical frames appear, for example, in the form of edge modes.
