While developing code in the formula tool (and perhaps elsewhere) it would be helpful to have the "parenthesis highlighting" function found in database software such as SSMS, DBeaver, SQL Developer etc. I.e. put the cursor next to a closing paren and the corresponding opening paren gets highlighted (or vice versa) - conversely if there is no corresponding paren nothing gets highlighted and you instantly know you've got a bug to fix (and where to fix it)!
