[Forminator Pro] Enhanced Formulae for Calculated fields

Hi,
I would like to request that we have slightly more complex calculations using if/then/else that way we can have select options for things like delivery and possibilities for free shipping if over a specified amount (and other things).

I know that Forminator is not intended to replace an eCommerce system, but if one of our clients only has 1 or 2 items for sale its ideal to have an order form in Forminator. I would just like to be able to do slightly more complex calculations on things like the shipping (or whatever else is needed).

Regards

Mark
