• Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?) None

Looks very good. Big fan of the mini belt under the sorting station!

There is a big "blocker wall" on two of the belts to stop the fish from progressing?

I think the walls might be there for the ease of working on the sorting contraption? Not sure, they were there originally.
