Hi @Shalm, hello to the Community!
It simply wants to be an example of the possibilities offered by FC in addition to those already suggested, no control over the rest.
Of course you can use the spredesheet, but in certain situations using a "fictitious" Sketch offers undeniable advantages: it allows me to have many numeric Combo Boxes and immediately appreciate their effects, not having to alternate the view between model view and spredesheet or divide the display in two windows.
