    Is it possible to add functionality for cell shading as an alternate form of notation for Fillomino in Penpa? It’s the sort of puzzle where colour-coding blocks seem like it’d work better than the standard notation techniques, especially for phone solvers.

      You can turn on “Surface” mode from the Tab menu to get most of this functionality, but right now I don’t know if there is an easy way (would need to be new code) to have colors be used for any answer checking in this puzzle style.
