Currently, the listing contains the Courant and Fourier numbers for the momentum equation, and the combined Courant/Fourier criterion. It could be interesting to also have this combined Courant/Fourier criterion for transported scalars. This might be especially relevant for buoyant scalars.

There's a DeprecationWarning from the test_combo_field tests on Python 3.8.
