Out of pure curiosity, what use do you have for this? I can't wrap my head around this being anything more than a shiny new thing. It doesn't have syntax highlighting, doesn't have keyboard shortcuts, and therefore seems to be worthless for anything other than markdown editing (for which I would rather just use my text editor).

Initially, i thought it had shortcuts and syntax highlighting. Anyway, i don't think it will be too long before they will add these features. But it's true, now is kind of useless.

My guess is that they're making sure this works before integrating it into the editor at large. Isn't that the most obvious thing to do with it?
