N2 - We present a concise description of the basic features of gravity-matter models based on the formalism of non-canonical spacetime volume-forms in its two versions: (a) the method of non-Riemannian volume-forms (metric-independent covariant volume elements) and (b) the dynamical spacetime formalism. Among the principal outcomes we briefly discuss: (i) quintessential universe evolution with a gravity-“inflaton”-assisted suppression in the “early” universe and, respectively, dynamical generation in the “late” universe of Higgs spontaneous electroweak gauge symmetry breaking; (ii) unified description of dark energy and dark matter as manifestations of a single material entity—a second scalar field “darkon”; (iii) unification of dark energy and dark matter with diffusive interaction among them; (iv) explicit derivation of a stable “emergent universe” solution, i.e., a creation without Big Bang; (v) mechanism for suppression of 5-th force without fine-tuning.
