### Abstract

In recent attempts to develop a dynamical analogue of the Toms-Winter conjecture for simple separable nuclear $$\mathrm{C}^*$$-algebras several interesting regularity properties for (generalized) topological dynamical systems have emerged. Most of these can be studied conveniently in the framework of topological groupoids. In this talk I will focus on two of them, almost finiteness and dynamical comparison. Moreover, I will explain how the passage from transformation groups to groupoids yields interesting new phenomena by looking at some examples coming from coarse geometry.
