@Jon, I haven't done anything about bus unfolding yet. Like unit selection, it requires some research into how to do menu conditionalization that's more flexible than the standard method (we can't very well have a condition for symbols-with-2-units, symbols-with-3-units, etc.)
If you want to take over the bus unfolding, then I can just copy your solution for unit selection. ;)
