I primarily use the free WordPress plugins for my blog. But I have just bought the Thrive Visual Editor plugin from Thrive Themes ($67). This plugin makes it easy to develop landing pages, lightboxes and even allows you to override the wordpress theme editor so you can develop content that doesn’t conform to the layout of your installed theme.
