So I sent the HT an email, and @Meg replied. (Thanks!)
Thanks so much for sharing this idea—it's a great one! I'll pass it on to the team.
Just as a heads up: our biggest priorities right now are building an iPhone editor and improving the web player. As part of the iPhone project, we might do some work on the editor to make it more powerful, like copy/paste, “self” variables, and more.
Things like adding images, comments, more sounds, and new characters are on our list but won’t be built for some time. But, we're always eager to add to our list so appreciate hearing from you.
