When writing a good amount of code, it is easy to get lost in a sea of parentheses. Just when you think you're all done, you get an error that can force you to scour through your code to find the missing, extra, or misplaced parenthesis.
A common feature today is to highlight a parenthesis when its partner is clicked on. This instantly lets you know if you have the wrong number of them and where.
I didn't think this was that important early on in Alteryx, at least for me. Formulas were meant to be short and easily readable at a glance. Now as I dig deeper, there's R, Python, SQL and other text-heavy inputs.
I don't need a full-fledged text editor in Alteryx, but I would love some quality of life features like parentheses matching.
