Calculation Field Preview - Show as how it will actually display

Would be helpful to have the calculation field preview to parse to what it will actually look like.

I usually have to go back and edit the code a few times to get the field to show how I want it too. It's not uncommon for calculations to take a while to change as well, making it tedious having to go back and forward.

Showing the RAW output can be helpful, but having an option to show how it will actually display would be super helpful too.

Could potentially remove a bit of load from your servers too.
