Make where you write functions an actual code editor
It is very frustrating writing anything other than a basic formula in Nintex forms for several reasons. The biggest frustration though is that there is no validation. Even Microsoft Excel gives you and indication that your formula is invalid. Also marking closing and opening brackets and parenthesis would be a huge help. It seems like it would be a simple task to implement this and a huge win for users.
Thanks for your suggestion.
I will update this idea if there are any updates to share.
Being able to indent, like a code editor, would also be phenomenal. When making complex formulas it gets confusing when everything is one line. Also the ability to comment out lines too (not sure if that exists?)
