Unless I was not searching under the proper keyword phrase, one feature I would love to see is expanding merge tags to better utilize the site settings - example “site name” would be very beneficial for use in notifications, so I can easily reuse the common forms we create and have them contain the site name merge tag.
note: I know there is a git project for adding to functions.php, but having this new merge tag in the system by default would be fantastic vs. having to copy over the code each time :).
