Change “Leave a Reply” text?

Greetings!
The plugin works great for me. I use it to remove the “website” field. I using it in conjunction with a reCAPTCHA plugin and they work well together.

The only other thing I’d like to see added is the ability to change the form text at the top (“Leave a Reply”). I’d love to see an added field in the plugin that would allow me to enter my own text to replace that text entirely with something of my own. Any way to add that?
