Excel could do this so much better though (and I think excel is the best candidate for visual scripting overhaul). The cell could have two parts; top parts is the function signature (other cells could reference by signature, or by cell number), bottom part is the code. Each cell is a function.

People put huge unreadable basic functions in that tiny box. It's such an obvious pain point, surprised it's never been addressed. Replace vba with c#, have a visual line linking cells to other cell references, bam million dollar product.
