  Our community has focused on two-body final states in $B$ & $D$ decays. The
SM produces at least the leading source of CP violation in $B$ transitions,
none has been established yet in charm decays. It is crucial to measure three-
and four-body FS with accuracy and to compare with predictions based on refined
theoretical tools. Correlations between different final states (FS) based on
CPT invariance are often not obvious, how to apply them and where. We have to
probe regional asymmetries and use refined parametrization of the CKM matrix.
One uses (broken) U- & V-spin symmetries for spectroscopy. The situations with
weak decays of hadrons are much more complex. The impact of strong
re-scattering is large, and it connects U- \& V-spin symmetries. Drawing
diagrams often does not mean we understand the underlying dynamics. We have to
probe the decays of beauty \& charm baryons. I discuss the `strategies' more
than the `tactics'.
