General note: I find the font colour in Miyagi really ugly on my eyes. It's basically "grey on grey". Dev Center, even with a smaller font size, is much easier to read.
In addition, it doesn't let me click the "Reader" button next to the URL when using Safari. That's one approach I use to read otherwise difficult-to-read web sites. Would be great if it supported that, at the very least (or better yet, had a better (darker) font colour)
