Speculations on higher Fukaya categories

We investigate a possible theory of higher Fukaya categories associated to $n$-shifted symplectic stacks, where $n\ge 0$. We consider two paradigmatic cases, the shifted cotangent stack of a smooth manifold and the coadjoint stack of a compact Lie group, drawing connections to the work of Teleman and 3D mirror symmetry. Our evidence includes some new results in $1$-shifted symplectic geometry.
