[racket] Would someone prefer paredit shortcuts?

 I used to write lisp code in emacs and enjoy paredit-mode.I tried to find an alternative for DrRacket but found nothing, so I decided to do it on my own. I has written a prototype in one day at https://github.com/yjqww6/drracket-paredit , and implemented Depth-Changing, Barfage & Slurpage shortcuts.
Either suggestion or criticism are appreciated.
