Support for e.g. f(cell((i+1),x), cell((i),x)) in the function dialog
Now, an expression like cell((i+1),x) - cell((i),x) works as expected which is great!
But support for f(cell((i+1),x)-cell((i),x)) in the function dialog would enable computing moving statistics like median[x(i-1),x(i), x(i+1)], where "f" means mean, median, stdev, sum, max etc. As the below screenshot shows, the function parser such formulas, but the results are wrong.
