I guess I would rather have something that was a bit more explicit and durable. of course, the cm offsets would be totally clutch during live editing, as seeing the effects of your actions is a great way to learn.... Blocky goes out of its way to generate readable code.

The argument still apply for command line, but I had a prototype of webkit console, that is to say, looks like qtconsole, 
but edit in code mirror, Mathjax, iframes… etc. 

Qt webkit is painfully slow, never had the time to look at chromium embedded.
