The text editor is the bane of WP. I use TinyMCE Advanced plugin, but not all themes support importing the CSS. It would be great to have a text editor that looks exactly like the site CSS. Or, at least one that has a default serif font in 12 or 14pt, like most sites use.

I also like Eric’s suggestion for a better AS3 interface. I have a member site with tons of vid tuts I’m about to launch.
