uhm, you need to the save the page to view the changes, so the āpreviewā button in the panel should actually be renamed to just āviewā, because there is no preview* before you saveā¦ Thats why jens did the Reveal pluginā¦
DO YOUR CHANGES
WATCH IT LIVE
SAVE(PUBLISH)
Well if you create a new page, and the status āInvisibleā you can view it and then make it visible, but if you want to do changes etcā¦ and preview you changes before SAVE(Publish it to the world), and the bonus of the Reveal plugin is that it is a āliveā preview, updates as you type etcā¦ No need to go back and forth between tabsā¦
