Maybe one day, but no promises. I did experiment with formulas in an earlier version, and it was promising, but there's a lot of things that need to be exactly right.

Also, I need to draw a line somewhere. I cannot turn the product into a spreadsheet, as I have chosen for performance as my main feature, which means it cannot do things like merged rows, merged columns, etc.

So if I'd implement formulas, people might expect more & more features, which I then cannot deliver...

(There are products out there that have basic formula support.)
