While the wordpress editor is great, it’s not completely WYSIWYG. Various CSS settings from the theme aren’t displayed in the editor.
Is there a plug-in that will make the editor more WYSIWYG by loading the CSS?
Even a plug-in that adds a frame in the post-edit page that shows the post being edited will be good enough. I just want to see how the post will look like without having to open multiple tabs on my browser.
Since version 3.0 WP allows to add custom stylesheet to visual editor.
