Does Morita theory hint higher modules for noncommutative ring?
As explained for example here
https://doi.org/10.1112/plms/s3-72.2.281
the most direct analogue of Morita equivalence for (connected) graded algebras actually boils down to graded isomorphism.
However …

Isomorphisms of quantum planes
Let $k$ be a field and $q\in k^{*}$. The quantum plane $k_{q}[x,y]$ is the algebra $k\langle x,y\rangle/\langle xy=qyx \rangle$ (i.e. the quotient of the free non-commutative $k$-algebra on two varia …
