Thanks. We have a text editor though; not sure if you saw it. If can operate from a separate window, and it hotswaps all the HTML/CSS/JavaScript you code, without any lag.

Our code editor is actually the open source "Ace editor" (http://ace.ajax.org).

Of course, not everybody wants to code inside their browser, and that's fine. For those that do, we aim to make pixelJET the best way to do that.
