There was a problem hiding this comment.
I just suggested a minor generalisation, otherwise LGTM.

In this PR, it is shown that left/right Kan extensions of functors `F : C ⥤ H` along a functor `L : C ⥤ D` are compatible with changing the functors `F` and `L` by isomorphic functors, by the precomposition with an equivalence `G : C' ⥤ C`, and postcomposition with an equivalence `D ⥤ D'`.
