This may be a dumb question, but why is the html editor in the standard version so much more complete/nicer than the one in the advanced version?

I don't mean to be insulting, but it seems like the advanced version is less complete and less polished. Is it new? Don't get me wrong advanced is better in nearly every other way.

The only feature that standard seems to be missing is inlining images that you attach (and are not available on a web server). Advanced does this, but unintuitively (via attachments, not an image button) and it seems a bit fragile.
