DOLFINx Expressions for von Mises stresses (interpolating stresses instead of projecting)
Reusable projections that illustrate the problem with projecting DG into Lagrange (maybe too little time)
local-solver with cached LU factorization (maybe a bit too advanced for the remainder of the tutorial)

Add function expressions for the Lagrange element basis functions shown in "An introduction to the unified form language"? Would make it clearer that the planes in the figure "First order Lagrange basis functions" are spanned by the basis functions
When printing the basix tabulations, specify what the array values printed are? (if I understood correctly they are the function values of the basis functions in the tabulated points?)
In the introduction under "The computational domain" it says "For now, we don’t know if we are solving the Poisson equation on..." but the impression from the start is that we are to solve a projection problem?
The "Code generation" chapter begins with "All the code in the previous section is Python code symbolically describing the variational form of the projection. This is why we in FEniCS rely on code generation." It's not entirely clear why we need code generation, is it because the code is symbolic and we need to convert the code to something we can evaluate?
Transition from "Code generation" chapter to "Mesh generation" is somewhat abrupt, but you might be planning to add something? Would suffice to e.g. just add a comment to what is being printed when you're inspecting the introduction.c code.
