"For the first time, you can use any interface to edit a Rails application directly on the web, rather than rewriting the code offline, then uploading it to your host."
This seems super cool, especially for rapid prototyping, but does Heroku support any source control? I would be pretty nervous about updating a live application on the fly like that, having made some incredibly stupid changes to live code in my younger days (and that involved three steps, as opposed to one).
My complaint with it when I was messing around with it was I wasn't about to sit the and type into a textfield and not use some-sort of editor. But it appears they fixed that. I just wonder how useful it will be to working on the deployed copy, I mean your site would be giving off all sorts of fun errors to the people coming to your site if your sitting there messing the the script.
